Technical Field

[0001] The invention relates to the technical field of hawthorn slicing, and in particular to a hawthorn slicing device. Background Art

[0002] Hawthorn is widely used as a food raw material, but mature hawthorn fruits cannot be stored for a long time and need to be processed in a certain process. The process of hawthorn processing is complicated, among which, the hawthorns are first screened, sorted and sorted. The hawthorns of suitable size are sorted one by one, and finally sliced. The thickness of the slices cut by the operator manually is easy to control, but the efficiency is relatively low.

[0003] The Chinese patent application document with publication number CN115890789A discloses a hawthorn slicer, including a straightening mechanism, a core removal mechanism and a slicing mechanism; the straightening mechanism includes a straightening bracket, a driven roller, a driving roller, a conveyor belt, a straightening shaft, a synchronous belt, a straightening motor and a driving motor; the driven roller and the driving roller are rotatably arranged on the straightening bracket, the conveyor belt is installed on the driven roller and the driving roller, the driving motor is installed on the straightening bracket and drives the driving roller to rotate, a number of material storage boxes are equidistantly arranged on the conveyor belt, the material storage boxes are cylindrical with a larger opening on the top, a number of straightening shafts are rotatably arranged on the straightening bracket, the synchronous belt is placed on the straightening shaft and drives the straightening shaft to rotate, the straightening motor is arranged on the straightening bracket and drives the straightening shaft to rotate; a spherical protrusion is arranged on the straightening shaft, and a number of straightening shafts are equidistantly arranged. This technical solution can straighten the hawthorns one by one with a high probability, efficiently and conveniently complete the core removal process, and reduce the loss of pulp.

[0004] The above technical solution slices the hawthorn by a slicing mechanism, and the blade on the slicing mechanism is fixed. When slicing the hawthorn, due to the inconsistent sizes of the hawthorns, when slicing the hawthorns, the uncut parts of the hawthorns with larger volumes are usually thicker, while the hawthorns with smaller volumes are sliced ​​thinner or may be crushed by the cutting knife. In summary, the hawthorn slicer in the prior art will cause a large difference in slice thickness when cutting the hawthorns. Summary of the invention

[0005] The present invention provides a hawthorn slicing device, aiming to solve the problem in the related art that when a hawthorn slicing machine slices hawthorn, the thickness of the slices varies greatly due to the size of the hawthorn.

[0006] A hawthorn slicing device comprises: a material tray and a slicing knife, wherein a pressing plate that moves up and down and is used to fix the hawthorn is provided on the top of the material tray, and a knife holder is also provided on one side of the material tray, and the slicing knife comprises a fixed blade and a moving blade, and two elastic members with the same elastic coefficient are provided at the upper and lower ends of the moving blade, the upper elastic member is connected to the pressing plate, and the lower elastic member is connected to the fixed blade; A mounting block is provided in the tool holder so as to slide up and down, the movable blade is rotatably provided on the mounting block and a torsion piece is provided between the movable blade and the mounting block, a restraining component for keeping the movable blade in a horizontal state is installed between the movable blade and the tool holder, and after the movable blade follows the mounting block to descend a certain distance, the movable blade loses the restraining force of the restraining component and deflects upward under the action of the torsion piece.

[0007] The effect is that by adjusting the position of the moving blade, when slicing hawthorns of larger and smaller volumes, the thickness of the two uppermost hawthorn slices after slicing are equally divided to keep the thickness of the hawthorn slices as much as possible; for hawthorns of too small volume, when slicing, the uppermost moving blade does not slice the hawthorns, thereby ensuring that the thickness of the hawthorn slices after slicing is uniform.

[0008] Preferably, the constraint assembly includes a slideway and a slider, the slideway is provided on the tool holder and extends in the up and down directions, the slider is fixedly connected to the movable blade and slides in the slideway, and a receiving groove connected to the slideway is provided at the bottom of the slideway; the movable blade is kept horizontal by the constraint assembly, and when the slider slides into the receiving groove, the movable blade is kept in an inclined state by the torsion member.

[0009] Preferably, the torsion member is a torsion spring, one end of which is connected to the moving blade, and the other end of which is connected to the mounting block; the moving blade is rotated to a tilted state by the torsion spring.

[0010] Preferably, the elastic member is a spring, the top of the upper spring is connected to the pressing plate, and the bottom of the lower spring is connected to the fixed blade; by arranging the spring, the movable blade is kept in the middle of the pressing plate and the top fixed blade, so that when the movable blade slices the hawthorn, the two top hawthorn slices have the same thickness.

[0011] Preferably, a baffle plate that slides left and right is provided on one side of the material tray, and a return spring is provided between the baffle plate and the material tray. By providing the baffle plate, the hawthorns are blocked when the blade slices the hawthorns, preventing the hawthorns from falling from the material tray.

[0012] Preferably, an electric push rod is also provided on one side of the material tray, and a push block is provided at the fixed end of the electric push rod; by providing the electric push rod, when the hawthorn slices are completed, the baffle is moved on the material tray through the push block to push the hawthorn slices that fall on the material tray off.

[0013] Preferably, the top surface of the material tray is provided with an arcuate groove, and the bottom of the pressing plate is provided with an arcuate pressing surface; when the hawthorn is fixed, the arcuate groove contacts the bottom of the hawthorn, and the arcuate pressing surface contacts the bottom of the hawthorn slices, reducing the probability of the hawthorn being crushed.

[0014] Preferably, the arc-shaped groove is arranged to be inclined upward from left to right; when the hawthorn falls on the arc-shaped groove, it rolls to the right and is blocked by the baffle to prevent the hawthorn from rolling off the material tray.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. When slicing hawthorn, place the hawthorn on the tray and move it toward the bottom of the pressing plate. When the pressing plate presses the hawthorn on the tray, if the volume of the hawthorn is larger than the volume of the standard hawthorn, the moving blade moves upward to make the thickness of the two hawthorn slices at the top the same after slicing to balance the problem of the hawthorn slice at the top being too thick after slicing; 2. When the volume of hawthorn is small, the movable blade moves downward to make the thickness of the two hawthorn slices at the top the same after slicing to balance the problem of the thin thickness of the hawthorn slice at the top after slicing; 3. When the volume of hawthorn is very small, the moving blade rotates upward and no longer cuts the hawthorn slices, thereby avoiding the problem that the two hawthorn slices at the top are thin when the moving blade slices the hawthorn.

[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] like Figure 1-Figure 7 As shown, a hawthorn slicing device includes a material tray 1, a plurality of slicing knives 2 arranged in the up and down directions, and a pressing plate 3; when slicing the hawthorn, the hawthorn is placed on the material tray 1 and fixed by the pressing plate 3, and then the slicing knife 2 is pushed toward the hawthorn to slice the hawthorn.

[0026] Specifically, an arc groove 11 is provided on the top surface of the material tray 1. When the hawthorn is put in, the hawthorn is placed in the arc groove 11 to prevent the hawthorn from rolling. The contact area between the hawthorn and the arc groove 11 is large, and the hawthorn can be prevented from breaking when the hawthorn is pressed by the pressing plate 3. A baffle 12 that slides left and right is also provided on one side of the material tray 1. A return spring 14 is provided between the baffle 12 and the material tray 1. When the hawthorn is cut by the slicing knife 2, the slicing knife 2 may push the hawthorn to move left and right. The baffle 12 can prevent the slicing knife 2 from pushing the hawthorn off the material tray 1. The arc groove 11 is tilted upward from left to right. When the hawthorn falls into the arc groove 11 , it rolls toward the baffle 12 to prevent the hawthorn from falling from the material tray 1 when it falls on the arc groove 11 .

[0027] An electric push rod 13 is also provided on one side of the material tray 1, and a push block 15 is provided at the fixed end of the electric push rod 13; when slicing the hawthorn, the electric push rod 13 pushes the material tray 1 toward the slicing knife 2 to cut the hawthorn. When the hawthorn slicing is completed, the electric push rod 13 drives the material tray 1 to move in the opposite direction. When the baffle 12 contacts the push block 15, the baffle 12 is pushed to move to the right and pushes the cut hawthorn slices on the material tray 1 off. Then the electric push rod 13 drives the material tray 1 to move to the material receiving position. At this time, the baffle 12 is reset to the left side of the material tray 1 under the action of the reset spring 14.

[0028] The pressing plate 3 is provided with an electric telescopic rod 31; the pressing plate 3 is driven by the electric telescopic rod 31 to move downward until the pressing plate 3 contacts the hawthorn. When the electric telescopic rod 31 contacts the hawthorn, the movement is stopped to prevent the pressing plate 3 from crushing the hawthorn. In a specific embodiment of the present invention, an arc-shaped pressing surface is provided at the bottom of the pressing plate 3. When the hawthorn is fixed, the surface in contact with the hawthorn is an arc-shaped surface. Compared with point contact, the surface in contact with the hawthorn is larger, so the hawthorn is prevented from rolling on the tray 1.

[0029] In a specific embodiment of the present invention, in order to facilitate the fixation of hawthorn by the pressing plate 3, when the hawthorn is put in, the hawthorn can be first screened by a screening device, and the downward moving distance of the electric telescopic rod 31 is adjusted according to the volume of the individual hawthorns put in. After the same batch of hawthorns of similar volume are put in, another batch of hawthorns of other volumes are put into the material tray 1. When the pressing plate 3 slices the hawthorn, the hawthorns of the same batch are basically the same, and the pressing plate 3 can fix all the hawthorns put on the material tray 1 at one time.

[0030] When slicing hawthorn, usually multiple blades are set to cut the hawthorn into multiple slices at a time. In this embodiment, we take setting three blades as an example to explain the slicing process. By setting three blades to cut the hawthorn into four slices at a time, when slicing hawthorn, due to the differences between individual hawthorns, multiple blades are set to be fixed. When slicing hawthorn, if the individual hawthorn is relatively large, the thickness of the top slice of hawthorn will be relatively thick after the top blade slices the hawthorn. If the individual hawthorn is relatively small, the thickness of the top slice of hawthorn will be relatively thin. Therefore, the thickness difference of hawthorn is relatively large when slicing hawthorn.

[0031] In a specific embodiment of the present invention, a knife holder 4 is provided on one side of the material tray 1, and two fixed blades 21 are fixedly provided on the knife holder 4. A movable blade 22 is also slidably provided on the knife holder 4, and the movable blade 22 is located above the two fixed blades 21. Elastic members 41 with the same elastic coefficient are respectively provided at the upper and lower ends of the movable blade 22. The upper elastic member 41 is connected to the pressing plate 3, and the lower elastic member 41 is connected to the fixed blade 21. In the initial position, the two elastic members 41 are in a natural state. At this time, when the hawthorn is cut, the three blades cut the hawthorn into four equal parts. The individual volume of the hawthorn is called the standard hawthorn volume. Of course, in other embodiments, four blades, five blades, etc. can be set to cut the hawthorn into five equal parts or six equal parts respectively. The specific setting can be made according to the needs. We explain the present invention according to the three slicing knives 2 cutting the hawthorn into four parts.

[0032] When the volume of the hawthorn is relatively large, that is, larger than the above-mentioned standard hawthorn volume, the electric telescopic rod 31 drives the pressing plate 3 to press the hawthorn. When the pressing plate 3 moves downward but does not reach the position for cutting the standard hawthorn, the two elastic members 41 will be stretched, and the movable blade 22 will move upward for a distance at this time. Since the elastic coefficients of the two elastic members 41 are the same, the movable blade 22 will be located in the middle of the pressing plate 3 and the top fixed blade 21. That is to say, when the movable blade 22 cuts the hawthorn, it will divide the hawthorn between the pressing plate 3 and the fixed blade 21 into two hawthorns. The thickness of the two hawthorns at the top after cutting is slightly thicker than the thickness between the fixed blades 21. If the top movable blade 22 is fixed at this time, the thickness of the remaining hawthorn slices is uniform, but the thickness of the top hawthorn slice will be relatively thick.

[0033] Similarly, when the volume of hawthorn is relatively small, after the pressing plate 3 fixes the hawthorn, the movable blade 22 will move downward for a distance. At this time, when the hawthorn is cut by the slicing knife 2, the thickness of the top two hawthorn slices will be slightly thinner than the thickness of the standard hawthorn slices, but the thickness of the top hawthorn slice will not be too thin.

[0034] When the volume of hawthorn is too small, when the movable blade 22 cuts the hawthorn, the thickness of the two uppermost hawthorn slices will be significantly smaller than the thickness of the standard hawthorn slices. At this time, the hawthorn slices cut by the passive blade 22 do not need to be cut again to ensure that the thickness of the hawthorn slices is within a reasonable range.

[0035] To solve the above problem, a mounting block 42 is slidably provided on the tool holder 4, and the movable blade 22 is rotatably provided on the mounting block 42. A torsion piece 43 is provided between the mounting block 42 and the movable blade 22, and the torsion piece 43 applies an upward torsion force to the movable blade 22. A constraint component 44 for keeping the movable blade 22 in a horizontal state is installed between the movable blade 22 and the tool holder 4; when slicing hawthorn, if the volume of hawthorn is too small, when the pressing plate 3 fixes the hawthorn, the elastic member 41 is compressed to a large deformation amount, and the movable blade 22 moves downward a large distance at this time. After the movable blade 22 moves a certain distance, it loses the constraint force of the constraint component 44 and rotates upward under the action of the torsion piece 43. At this time, when the slicing knife 2 and the hawthorn are close to each other, the movable blade 22 will not cut the hawthorn due to its upward rotation. Taking three slicing knives 2 as an example, the three slicing knives 2 cut the hawthorn into three slices, and the thickness of each slice will not differ too much.

[0036] Specifically, the constraint assembly 44 includes a slide 441 and a slider 442. The slide 441 is provided on the tool holder 4 and extends in the up and down directions. The slider 442 is fixedly connected to the movable blade 22 and slides in the slide 441. A receiving groove 443 connected to the slide 441 is provided at the bottom of the slide 441. When the slider 442 slides in the slide 441, the slider 442 keeps sliding up and down under the constraint of the slide 441. At this time, the movable blade 22 keeps a horizontal state, and the movable blade 22 can slice the hawthorn. When the slider 442 slides down out of the slide 441, the slider 442 rotates under the action of the torsion member 43 and causes the movable blade 22 to rotate upward. When the slicing knife 2 slices the hawthorn, the movable blade 22 rotates upward and the movable blade 22 will not slice the hawthorn.

[0037] Specifically, the torsion member 43 is a torsion spring, one end of which is connected to the movable blade 22 , and the other end of which is connected to the mounting block 42 ; when the movable blade 22 loses its restraining force, the movable blade 22 rotates upward under the action of the torsion spring.

[0038] In other embodiments of the present invention, the constraint component 44 can be a driving motor, and the moving blade 22 is fixedly arranged at the output end of the driving motor. A distance sensor is installed on the driving motor. When the moving blade 22 moves downward for a distance exceeding a certain value, the driving motor is used to rotate the moving blade 22 to an inclined state. When the moving blade 22 moves upward, the driving motor is used to rotate the moving blade 22 to a horizontal state.

[0039] Working principle: When slicing the hawthorn, the hawthorn is placed on the material tray 1 and moved toward the bottom of the pressing plate 3. When the pressing plate 3 presses the hawthorn on the material tray 1, if the volume of the hawthorn is larger than the volume of the standard hawthorn, the movable blade 22 moves upward to make the thickness of the two hawthorn slices at the top after slicing the same to balance the problem of the thickness of the hawthorn slices at the top being too thick after slicing. When the volume of the hawthorn is small, the movable blade 22 moves downward to make the thickness of the two hawthorn slices at the top after slicing the same to balance the problem of the thin thickness of the hawthorn slices at the top after slicing. When the volume of the hawthorn is very small, the movable blade 22 rotates upward and the movable blade 22 no longer cuts the hawthorn slices to avoid the problem of the two hawthorn slices at the top being thin when the movable blade 22 slices the hawthorn.

[0040] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
