Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a cutting and processing machine. Background Technology
[0002] To save time during the food preparation stage, various food preparation devices have emerged. However, for Chinese cooking, considering the diversity of ingredients, the food preparation process is even more varied.
[0003] The food preparation equipment in the related technology includes a base and a receiving component and a cutting blade mounted on the base. The receiving component has a receiving groove for holding food. During cutting, the food is first placed at the bottom of the receiving groove, and then the cutting blade is pressed down to cut the food. In order for the cutting blade to completely cut the food in the receiving groove, a relief groove is usually recessed at the bottom of the receiving groove so that at least the blade part of the cutting blade enters the relief groove. This avoids contact between the cutting blade and the bottom of the receiving groove while ensuring that the food is completely cut. However, during the cutting process, some debris will enter the relief groove. Due to the large depth of the receiving groove, the relief groove is difficult to clean later, which affects the user experience.
[0004] Therefore, it is urgent to research a cutting and processing machine to solve the above problems. Utility Model Content

[0037] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.
[0038] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0039] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.
[0040] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.
[0041] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values not using relative terms should also be disclosed as specific values with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.
[0042] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.
[0044] like Figures 1 to 6As shown, this embodiment provides a food preparation machine to improve cleaning convenience and enhance user experience. The automatic food preparation machine can be used independently to cut ingredients during food preparation, or it can be applied to cooking robots to work with the robot's cooking mechanism to complete ingredient cutting and cooking, improving the automation and efficiency of cooking, meeting users' needs for uniformly cut ingredients, and facilitating the preparation of various dishes to improve user satisfaction. The food preparation machine includes a base 100, a support component 200, a frame 300, and a cutting assembly 400. The support member 200 is located on the base 100 and includes a support seat 210 and a support protrusion 220 located on the support seat 210. The frame 300 is detachably connected to the support seat 210 and surrounds the outer periphery of the support protrusion 220. The frame 300 and the support seat 210 form a receiving groove 315. Along the length of the base 100, the support protrusion 220 has a through first clearance groove 221 and the frame 300 has a through second clearance groove 316. The second clearance groove 316 connects to the receiving groove 315. The cutting assembly 400 includes a cutting bracket 410 and a cutting blade 420 located on the cutting bracket 410. From top to bottom, the cutting blade 420 can enter the receiving groove 315 and the first clearance groove 221 to cut the food in the receiving groove 315. The two ends of the cutting blade 420 are located in the second clearance grooves 316 on both sides of the frame 300. The second clearance groove 316 corresponds to the first clearance groove 221.
[0045] With the separate arrangement between the carrier 200 and the frame 300, once the food is cut, the frame 300 can be easily removed from the carrier 200 to clean the debris in the first clearance groove 221, reducing cleaning difficulty and improving user experience.
[0046] Regarding the connection method between the support member 200 and the frame 300, in some embodiments, the top of the support base 210 is provided with two plug-in members 211, which are spaced apart along the length direction of the base 100. The bottom of both sides of the frame 300 along the length direction of the base 100 extend outward to form a front bottom plate 320 and a rear bottom plate 330, respectively. Each of the front bottom plate 320 and the rear bottom plate 330 is provided with a plug-in hole 321, and the two plug-in members 211 are respectively inserted into the two corresponding plug-in holes 321. The above arrangement helps to realize the quick assembly and disassembly of the support member 200 and the frame 300, and improves cleaning efficiency. In other words, the frame 300 includes a frame body 310 and a front bottom plate 320 and a rear bottom plate 330 located at the lower end of the frame body 310. Along the length direction of the base 100, the front bottom plate 320 and the rear bottom plate 330 are located at the front end and rear end of the frame body 310, respectively.
[0047] In some embodiments, the carrier 200 is detachably disposed on the base 100. This arrangement facilitates the removal of the carrier 200 from the base 100 for cleaning. During disassembly, the frame 300 can be removed from the carrier 200 first, and then the carrier 200 can be removed from the base 100; alternatively, the frame 300 and the carrier 200 can be removed from the base 100 together first, and then the frame 300 can be removed from the carrier 200.
[0048] During use, when the slitting blade 420 is withdrawn, that is, when the slitting blade 420 moves upward, friction is generated between it and the food, thereby causing the food to move upward. There may also be friction between the food and the frame 300. To prevent the frame 300 from separating from the support 210, in some embodiments, the support member 200 also includes a stop member 230. One end of the stop member 230 is rotatably disposed in one of the two plug-in members 211. The front bottom plate 320 has a notch that communicates with the plug-in hole 321. The notch 322 connects to the insertion hole 321, which corresponds to the insertion member 211 connected to the stop member 230. The other end of the stop member 230 can rotate above or beside the notch 322. When the other end of the stop member 230 rotates above the notch 322, the insertion member 211 can be inserted into the insertion hole 321. When the other end of the stop member 230 rotates to the side of the notch 322, it restrains the insertion member 211 from being pulled out of its corresponding insertion hole 321. This arrangement limits the frame 300 to the stop member 230, preventing the frame 300 from separating upwards from the support base 210, thus improving safety during use.
[0049] Regarding the connection method of the stop member 230, in some embodiments, the carrier member 200 further includes a stop screw 240, the carrier seat 210 has a carrier channel, the connector 211 has a connector channel, and the stop screw 240 passes through the carrier channel and the connector channel in sequence, and is screwed into the stop screw hole of the stop member 230. The carrier seat 210 and the connector 211 are sandwiched between the nut of the stop screw 240 and the stop member 230. The tightening degree of the stop screw 240 can control the force required for the stop member 230 during the knob turning process.
[0050] In some embodiments, the other of the two connectors 211 includes a connector body 2111 and a connector limiting arm 2112. The connector body 2111 extends along the height direction of the base 100, and the connector limiting arm 2112 is located at the top of the connector body 2111 and extends away from the other connector 211. This arrangement allows the frame 300 to be simultaneously limited by the stop member 230 and the connector limiting arm 2112, improving the stability of the connection between the frame 300 and the support member 200. Of the two connectors 211, the one located on the front side has a columnar structure and has a connector channel; the one located on the rear side includes a connector body 2111 and a connector limiting arm 2112. Further, both the connector body 2111 and the connector limiting arm 2112 are cuboid structures.
[0051] The slitting bracket 410 has a slitting channel 411 in which a slitting blade 420 is mounted. Along the width direction of the base 100, the width of the slitting channel 411 is greater than the width of the frame 300. This arrangement helps to reduce the height of the slitting blade 420. In some embodiments, the slitting blade 420 can be a rigid filament structure. For example, the slitting blade 420 can be a steel wire.
[0052] The cutting assembly 400 includes a plurality of cutting blades 420, which extend along the length of the base 100 and are spaced apart along the width of the base 100. This arrangement allows the cutting assembly 400 to cut the food in the receiving groove 315 into several portions in a single pressing action, greatly improving the cutting efficiency.
[0053] The slitting bracket 410 is hinged to the base 100 via a hinge shaft 430. The hinge shaft 430 is located on the rear side of the frame 300. The frame 300 includes a front sidewall 311 and a rear sidewall 312 spaced apart along the length of the base 100, and a left sidewall 313 and a right sidewall 314 spaced apart along the width of the base 100. From bottom to top, the front sidewall 311 is inclined toward the rear sidewall 312.
[0054] The above-mentioned arrangement ensures that the squeezing force exerted on the food during the downward pressing of the cutting support 410 has a forward component. Since the front sidewall 311 is tilted backward, the force acting on it has an upward component, which helps reduce the possibility of the front sidewall 311 flipping forward under pressure and improves its stress distribution. Furthermore, during the downward pressing and rotation of the cutting support 410, the food is first squeezed from the rear, causing it to move forward and upward. This arrangement also reduces the likelihood of the food being squeezed from the rear by the cutting blade 420 and then slipping out of the gap between the front sidewall 311 and the cutting blade 420. Further, both the front sidewall 311 and the rear sidewall 312 are provided with a plurality of second clearance grooves 316, arranged in a one-to-one correspondence between the plurality of second clearance grooves 316 in the front sidewall 311 and the plurality of second clearance grooves 316 in the rear sidewall 312. During the downward rotation of the slitting bracket 410, the slitting blade 420 first enters the second clearance groove 316 in the front sidewall 311, and then enters the second clearance groove 316 in the rear sidewall 312.
[0055] In some embodiments, the front sidewall 311 has a curved structure that protrudes outward in a direction away from the receiving groove 315. This arrangement causes the food to move forward and then converge towards the concave area, further reducing the possibility of the food moving upward out of the receiving groove 315.
[0056] During use, as the slitting bracket 410 is pressed down, the contact between the slitting bracket 410 and the base 100 restricts the lowest position of the slitting bracket 410. To ensure that the slitting bracket 410 is in its lowest position, the slitting blade 420 enters the first clearance groove 221. The slitting bracket 410 rotates between the clearance position and the lowest position. In some embodiments, the bottom of the first clearance groove 221 is above the bottom of the second clearance groove 316. This arrangement prevents the second clearance groove 316 from affecting the slitting blade 420. In other embodiments, the bottom of the first clearance groove 221 is flush with the bottom of the second clearance groove 316. In some embodiments, the width of the first clearance groove 221 is greater than the width of the second clearance groove 316. This arrangement minimizes the possibility of the slitting blade 420 contacting the sidewall of the first clearance groove 221 even if it tilts to the side.
[0057] In some embodiments, the cutting machine further includes a drive member and a moving member 110. The moving member 110 is slidably disposed on the base 100 and reciprocates along the length direction of the base 100. The drive member is disposed on the base 100, and its output end is connected to the moving member 110 in a transmission manner. A support member 200 is disposed on the moving member 110. Specifically, the moving member 110 has a moving channel 111, the outer diameter (diameter of the circumscribed circle) of the moving channel 111 is smaller than the outer diameter of the support 210, and the bottom of the support 210 has an insertion protrusion 250, the outer diameter of which is smaller than the outer diameter of the support 210. The support 210 is placed on the moving member 110, and the insertion protrusion 250 is inserted into the moving channel 111. The above arrangement enables the ingredients to reciprocate along the length direction of the base 100 during the cutting process, thereby improving the cutting efficiency. In this embodiment, the outline of the projection of the moving channel 111 on the horizontal plane is rectangular. Along the length direction of the base 100, the length of the moving channel 111 is less than the length of the support 210. Along the width direction of the base 100, the width of the moving channel 111 is less than the width of the support 210.
[0058] Exemplarily, the cutting and slicing machine also includes a cam and a connecting rod. The driving element is a motor. The cam is located at the output end of the driving element, and one end of the connecting rod is hinged to the cam, while the other end is hinged to the moving element 110. This arrangement converts the circular motion of the driving element into the linear motion of the moving element 110. The cam includes a disk and a pin. The axis of the disk is collinear with the output shaft of the motor, and the pin is located outside the axis of the disk and parallel to it. One end of the connecting rod is hinged to the pin. In other embodiments, the moving element 110 can be directly driven by a cylinder or an electric push rod.
