[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] like Figure 1As shown, the present invention is an electric cutting machine, comprising a frame 1, and a transmission mechanism 2, a tool holder assembly and a press-fitting mechanism arranged on the frame 1, wherein the press-fitting mechanism is connected to one end of a transmission rack 3 of the transmission mechanism, wherein the press-fitting mechanism is caused to reciprocate through the transmission rack 3.

[0032] Furthermore, the transmission mechanism of the present invention also includes a motor and a gear, the motor is connected to the gear; the transmission rack is meshed with the gear; when the motor rotates, the transmission rack reciprocates along the gear, so that the pressing mechanism connected to one end of the transmission rack is synchronously linked.

[0033] Further, such as Figure 2 As shown, the pressing mechanism of the present invention includes a fixed plate 4, a pressing cap 5 and a guide rod 6, the fixed plate 4 is fixedly connected to one end of the transmission rack 3, the pressing cap 5 is arranged at the bottom of the fixed plate 4, and the guide rod 6 is respectively connected to the fixed plate 4 and both sides of the tool holder assembly and one end thereof is connected to the frame.

[0034] Further, such as Figure 1 , Figure 2 As shown, the tool holder assembly of the present invention includes an upper tool holder 7 and a lower tool holder 8, the upper tool holder 7 is located below the pressure cap 5, and the guide rods 6 are respectively connected to the two sides of the upper tool holder 7; the lower tool holder 8 is arranged between one end of the guide rods 6 and corresponds to the position of the upper tool holder 7.

[0035] Further, such as Figure 2 As shown, the present invention also includes a hook mechanism, which includes a hook 9, a hook seat 10, a hanging plate 11, a pull rope 12 and a handle 13. The hook seats 10 are respectively arranged on both sides of the bottom of the fixed plate 4, and the hooks 9 are respectively hinged to one side of the hook seat 10; through holes are respectively opened on both sides of the fixed plate 4, one end of the hook 9 extends out of the through holes, one end of the pull rope 12 is fixed to one end of the hook 9 on one side and passes around one end of the hook 9 on the other side, and the pull rope 12 forms a linkage between the hooks 9 on both sides; the hanging plates 11 are respectively arranged on both sides of the upper tool holder 7, and in the hanging buckle state, the other end of the hook 9 is buckled and connected with the hanging plate 11; wherein, the other end of the pull rope 12 is a free end and is located on the same side as one end of the pull rope 12, and the handle 13 is arranged at the end of the other end of the pull rope 12.

[0036] It should be pointed out that the hanging plate of the present invention is in the shape of a frustum.

[0037] It should be further pointed out that the initial state of the present invention is that the upper tool holder and the lower tool holder are located at the bottom, the pressing mechanism is located at the top (close to the transmission mechanism), the object to be cut is placed under the pressing cap through the fixed needle, the pressing mechanism descends at a certain speed, and the pressing cap gradually presses down the object to be cut, and the object to be cut is cut from the bottom by the blade of the upper tool holder and the steel wire of the lower tool holder.

[0038] Furthermore, the hooks on both sides of the fixed plate are lowered along with the pressing mechanism until they abut against the periphery of the hanging plate. Since the hanging plate is in the shape of a cone, the bottom of the hook rotates outward along the cone slope until it completely slides over the cone slope, and then it is reset and rotated inward, so that the hook and the hanging plate form a buckling relationship. After the buckling relationship between the pressing mechanism and the upper tool holder is formed, the gear of the transmission mechanism rotates in the opposite direction, driving the transmission rack to rise, and the pressing mechanism and the upper tool holder rise synchronously, and at the same time, the fixed pin of the pressure cap and the upper tool holder pull up the cut object.

[0039] Furthermore, when the pressing mechanism rises to the initial position and then stops, at this time, by pulling the handle of the pull rope, since the pull rope is connected to the tops of the hooks on both sides, when the pull rope is pulled, the top of the hook rotates inward, causing the bottom of the hook to rotate outward, thereby achieving separation from the hanging plate. After the upper tool holder is no longer engaged with the hook, it uses its own gravity to descend.

[0040] Furthermore, based on the above-mentioned upper tool holder descending principle, in order to prevent the upper tool holder from descending too fast, Figure 1 As shown, the present invention also includes a buffer mechanism 14, the buffer mechanism 14 includes a traction rope and a buffer, one end of the traction rope is connected to the buffer, and the other end is connected to the upper tool holder 7. During the descent of the upper tool holder 7, the buffer is used to make the lower tool holder descend smoothly. Among them, the buffer used in the present invention is similar to the buffer used for slow descent in the prior art.

[0041] It should be pointed out that, further, Figure 1 As shown, the present invention is further provided with a fixing rod 15 and a mounting plate 16 , one end of the fixing rod 15 is connected to the frame 1 , and the other end of the fixing rod 15 is connected to the mounting plate 16 ; the transmission mechanism is arranged in the mounting plate 16 .

[0042] It should be pointed out that the guide rod of the present invention plays a stabilizing role in the process of the pressing mechanism and the upper tool holder descending or ascending.

[0043] Further, such as Figure 1 As shown, the upper blade holder 7 of the present invention is provided with a plurality of blades 71 arranged at equal distances, and the lower blade holder is provided with a plurality of steel wires arranged at equal distances.

[0044] It should be pointed out that the blade and the steel wire of the present invention are respectively located in two planes and are arranged vertically and horizontally with respect to each other. Such an arrangement is conducive to cutting the object to be cut into strips.

[0045] Further, such as Figure 3 As shown, sliding mechanisms are respectively provided on both sides of the bottom of the lower tool holder 8 of the present invention, and the sliding mechanism includes a connecting rod 19, a slider 20 slidably connected to the connecting rod 19, and a spring (not shown in the figure), the top of the slider is connected to the bottom of the lower tool holder, and the spring is passed through the connecting rod 19 and is respectively arranged on both sides of the slider 20.

[0046] It should be noted that the lengths of the springs on both sides are not the same, wherein the spring at the front end is slightly shorter than the spring at the rear end.

[0047] Further, such as Figure 4 As shown, in order to ensure that the bottom of the pressure cap 5 of the present invention is provided with a plurality of extending fixing pins 21. The fixing pins are used to fix the radish and position the radish substantially at the center of the knife holder to ensure the smooth completion of the cutting.

[0048] Further, as a preferred technical solution, Figure 2 As shown, the present invention is also provided with a trigger rising reset mechanism, which is composed of a trigger rod 17 and a trigger switch 18. The trigger rod 17 is arranged on one side of the fixed plate 4, and the trigger switch 18 is located on the frame and its position corresponds to the trigger rod 17. When the pressing mechanism moves downward until the trigger rod 17 and the trigger switch 18 are completely abutted, the trigger switch sends an upward signal to the transmission mechanism, so that the pressing mechanism and the upper tool holder move upward synchronously.

[0049] Further, as a preferred technical solution, Figure 5 As shown, the present invention is also provided with a material return mechanism. Specifically, a pair of springs 22 are provided on both sides of the top of the fixing plate 4 of the present invention, and a pair of guide posts 23 are provided at the bottom of the mounting plate 16 corresponding to the positions of the pair of springs 22.

[0050] It should be noted that the present invention can be specifically used for cutting radishes, especially white radishes.

[0051] Example

[0052] When the present invention is in an initial state, the pressing mechanism is located at the top of the machine, close to the transmission mechanism, and the upper knife holder and the lower knife holder are located directly below the pressing mechanism. A worker inserts the object to be cut into the fixing pin on the pressing cap so that the object to be cut can be fixed (the object to be cut in the example here is white radish); when the present invention is started, the gear of the transmission mechanism starts to rotate, driving the transmission teeth meshing therewith to move downward, causing the pressing mechanism connected to the transmission teeth to descend synchronously, and after descending for a period of time, the pressing cap presses the white radish into the blade on the upper knife holder, and the bottom of the white radish is cut from bottom to top, and the pressing cap continues to press down, and the white radish cut by the upper knife holder contacts with the steel wire of the lower knife holder and continues to be cut, and because the blade and the steel wire are arranged vertically and horizontally between two planes, the cut white radish forms strips.

[0053] It should be pointed out that in order to ensure that the present invention is suitable for white radishes of different shapes, for example, some white radishes are curved (for example, "S" shape), therefore, the present invention is provided with a sliding mechanism. When the white radish is continuously pressed down to the lower knife holder by the pressure cap, if the white radish itself has a large curvature, the slider can have a certain displacement on the connecting rod. Since the white radish has a certain hardness, after contacting the steel wire of the lower knife holder, it will apply force to the lower knife holder, and the slider can provide a certain displacement. The spring can allow the slider to reset after the position occurs, so as to better cut the white radish and prevent the white radish from hanging on the steel wire.

[0054] It should be pointed out that when the pressing mechanism descends to a certain position, the hook abuts against the edge of the hanging plate, and the pressing mechanism continues to descend, and the hook slides along the inclined edge of the hanging plate. This process causes the top of the hook to rotate inward, and conversely, the bottom of the hook rotates outward until the hook is separated from the inclined edge of the hanging plate and resets under the hook's own gravity. At this time, the bottom of the hook forms a buckle fit with the hanging plate.

[0055] It should be further pointed out that after the above-mentioned engagement is formed, the trigger rising and resetting mechanism provided in the present invention should be started synchronously, that is, when the bottom of the hook is engaged with the hanging plate, the trigger rod should fully press the trigger switch, thereby sending an upward signal to the transmission mechanism, and the gear rotates in the opposite direction, driving the transmission rack to rise, and finally realizing the synchronous upward movement of the pressing mechanism and the upper tool holder.

[0056] It should be further pointed out that, when the above-mentioned pressing mechanism and the upper knife holder rise to the initial position of the pressing mechanism, the present invention stops; at this time, in order to reset the upper knife holder and prepare for the next cutting, the staff pulls the handle on the pull rope. Since the pull rope is connected to the top of the hooks on both sides, when the pull rope is pulled, the top of the hook rotates inward, causing the bottom of the hook to rotate outward, thereby achieving separation from the hanging plate. After the upper knife holder is no longer engaged with the hook, it uses its own gravity to drop downward.

[0057] It should be further pointed out that when the cutting is completed, the white radish is still connected to the pressing cap because it is fixed on the fixing needle. In order to ensure that the staff can smoothly remove the white radish, when the pressing mechanism resets upward, the pressing mechanism continues to move upward, and the spring column is compressed and deformed after contacting the bottom of the mounting plate until the pressing mechanism is reset and stops. At this time, due to the addition of the spring columns on both sides as force points, the staff can relatively easily remove the white radish from the pressing cap of the pressing mechanism.

[0058] Finally, in order to avoid danger, the present invention provides a buffer mechanism, through the action of the buffer, the upper tool holder can maintain a stable descent during the descent process.

[0059] For those skilled in the art, various corresponding changes and modifications can be made according to the above technical solutions and concepts, and all of these changes and modifications should be included in the protection scope of the claims of the present invention.
