Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

They are used only for the convenience of describing this application and do not require this application to be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. The terms "connected" and "linked" used in this application should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0024] A bone saw includes a frame and a drive wheel and a driven wheel mounted on the frame, as well as a band saw fitted between the drive wheel and the driven wheel. The drive wheel rotates, driving the band saw to cut the food. With increased use, the band saw deforms; specifically, it stretches, resulting in decreased tension. Reduced tension causes the band saw to bounce when cutting food, leading to a wider kerf, increased food scraps, and uneven cuts, affecting the cutting quality. Furthermore, when the band saw reaches the end of its service life or is accidentally damaged, it needs to be replaced. However, replacing a band saw presents installation difficulties.

[0025] To address the aforementioned issues, this application provides a food cutting device capable of electrically tensioning a band saw.

[0026] Please refer to Figures 1 to 5 ,in, Figure 1 This is a schematic diagram of the food cutting device according to an embodiment of the present application from one perspective; Figure 2 This is a schematic diagram of the nose section of the device according to an embodiment of this application, viewed from one perspective. Figure 3 This is a schematic diagram of the internal structure of the food cutting device according to an embodiment of this application; Figure 4 This is a schematic diagram of the food cutting device according to an embodiment of this application from another perspective; Figure 5 This is a schematic diagram of the internal structure of the head unit according to an embodiment of this application.

[0027] This application provides a food cutting device, including a frame 1, a cutting assembly 2, and a tensioning assembly 3. The frame 1 includes a body 11 and a head 12. The body 11 is provided with a cutting table 111, and the head 12 is connected to the body 11 and located above the cutting table 111. The head 12 is provided with control buttons. The cutting assembly 2 includes a power element, a drive wheel 21, a driven wheel 22, and a band saw 23. The power element is disposed inside the body 11, the drive wheel 21 is disposed on the power element, and the driven wheel 22 is disposed on... Inside the head 12, the band saw 23 is connected to the drive wheel 21 and the driven wheel 22 respectively. The tensioning assembly 3 includes a guide 31, a carrier 32 and a linear drive element 33. The guide 31 is disposed inside the head 12 and extends toward the cutting table 111 to provide guidance. The carrier 32 is slidably engaged with the guide 31 and is connected to the driven wheel 22. The linear drive element 33 is connected to the carrier 32 and the control button respectively, and is used to drive the carrier 32 to slide under the control of the control button to tension the band saw 23.

[0028] When cutting ingredients, place them on the cutting table 111. The power element drives the drive wheel 21 to rotate, and the drive wheel 21 drives the driven wheel 22 to rotate through the band saw 23. The part of the band saw 23 located between the drive wheel 21 and the driven wheel 22 can cut the ingredients.

[0029] When tension needs to be adjusted, press the control button, and the linear drive element 33 provides linear drive force, which can push the carrier 32 to move away from the cutting table 111 along the guide of the guide 31, thereby driving the driven wheel 22 away from the driving wheel 21 and realizing the tension of the band saw 23.

[0030] When band saw 23 needs to be replaced, pressing the control button retracts the linear drive element 33, causing the support member 32 to descend under its own weight. This moves the driven wheel 22 closer to the drive wheel 21, reducing the distance between the drive wheel 21 and the driven wheel 22. The old band saw 23 can then be removed from the drive wheel 21 and the driven wheel 22, and the new band saw 23 can be fitted onto them. Pressing the control button extends the linear drive element 33, providing an upward (away from the cutting table 111) linear drive force, which moves the driven wheel 22 away from the drive wheel 21, thus tensioning the band saw 23.

[0031] For example, the control buttons may include an emergency stop button 121, a start / stop button 122, a first speed button 123, a second speed button 124, an up button 125, and a down button 126. The emergency stop button 121 is connected to the power element; pressing the emergency stop button 121 stops the operation of the power element. The start / stop button 122 is connected to the power element; pressing the start / stop button 122 controls the operation and stop of the power element. After the power element stops when the emergency stop button 121 is pressed, the start / stop button 122 becomes inactive; the emergency stop button 121 must be pressed again for the start / stop button 122 to control the operation and stop of the power element. The first speed button 123 and the second speed button 124 are both connected to the power element. Pressing the first speed button 123 causes the band saw 23 to cut the food at a first speed; pressing the second speed button 124 causes the band saw 23 to cut the food at a second speed, thus adjusting the cutting speed of the food. Both the up button 125 and the down button 126 are connected to the linear drive element 33. When the up button 125 is pressed, the linear drive element 33 extends, which can drive the driven wheel 22 away from the driving wheel 21; when the down button 126 is pressed, the linear drive element 33 retracts, which can drive the driven wheel 22 closer to the driving wheel 21.

[0032] For example, the power element is an electric motor. The linear drive element 33 is an element capable of providing linear driving force, and can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0033] In the technical solution of this application embodiment, the driven wheel 22 is mounted on the support member 32. The linear drive element 33 can push the support member 32 to slide along the guide member 31, causing the driven wheel 22 to move away from or closer to the drive wheel 21, thereby adjusting the tension of the band saw 23. This not only improves the cutting quality but also facilitates the replacement of the band saw 23. The linear drive element 33 is connected to a control button, which can control the operation of the linear drive element 33, thereby realizing the electric adjustment of the tension.

[0034] like Figure 5 As shown, in some embodiments of this application, the guide member 31 includes a mounting part 311 and a guide part 312. The mounting part 311 is connected to the machine head 12. The guide part 312 is in the shape of a round rod and slides in cooperation with the guide hole of the carrier 32. The axis of the guide part 312 is perpendicular to the cutting table surface 111. The first end of the guide part 312 is connected to the mounting part 311, and the second end of the guide part 312 is a free end and is provided with an inclined surface. The second end is located between the first end and the cutting table surface 111.

[0035] The guide component 31 is a one-piece structure, which can be formed by machining the mounting part 311 and the guide part 312 as a single unit. Specifically, the mounting part 311 is rectangular and can be milled, while the guide part 312 is rod-shaped and can be turned. Alternatively, the guide part 312 and the mounting part 311 can be machined separately and then joined together by riveting, welding, or bolting. When the guide component 31 is connected to the machine head 12, it can be fastened to the machine head 12 by bolting.

[0036] In the technical solution of this application embodiment, the guide portion 312 is in the shape of a round rod and can be inserted into the guide hole of the carrier 32, slidingly engaging with the guide hole to guide the sliding of the carrier 32, so that the driven wheel 22 approaches or moves away from the driving wheel 21. The second end of the guide portion 312 is provided with a bevel, which facilitates insertion into the guide hole of the carrier 32 during assembly, making installation convenient. In addition, the second end of the guide portion 312 is located between the first end and the cutting table surface 111. If the band saw 23 breaks accidentally, causing the driven wheel 22 and the carrier 32 to move upward (away from the driving wheel 21), the mounting portion 311 can provide a limiting function for the carrier 32, preventing the carrier 32 from detaching from the guide portion 31, thereby improving safety.

[0037] like Figure 5 As shown, in some embodiments of this application, the linear drive element 33 is an electro-hydraulic actuator, and the extension and retraction direction of the linear drive element 33 is perpendicular to the cutting table surface 111.

[0038] In the technical solution of this application embodiment, the electro-hydraulic actuator can be fixedly installed inside the machine head 12, for example, by means of bolt connection. The extension and retraction direction of the electro-hydraulic actuator is set perpendicular to the cutting table surface 111, so that the direction of force application is consistent with the sliding direction of the bearing member 32 when adjusting the tension, which can avoid the generation of force in other directions, making the guide member 31 more durable, less prone to bending, and improving its service life.

[0039] like Figure 5 As shown, in some embodiments of this application, the tensioning component 3 further includes an elastic component 34. The elastic component 34 is disposed between the carrier 32 and the linear drive element 33, and is connected to the carrier 32 and the linear drive element 33 respectively. The elastic component 34 includes a plurality of pressure springs, and the axis of the pressure springs is perpendicular to the cutting table surface 111.

[0040] For example, the number of compression springs can be three, and the three compression springs are arranged parallel to each other along their longitudinal axes. The number of compression springs can also be two, four, etc. The number of compression springs is preferably three, which can balance the convenience of assembly and the uniformity of force application.

[0041] For example, when the elastic component 34 is installed between the carrier 32 and the linear drive element 33, the elastic component 34 may be welded to the bottom of the carrier 32 and in separable contact with the linear drive element 33. After assembly, the elastic component 34 is in a compressed state between the linear drive element 33 and the carrier 32, and is always in contact with the linear drive element 33.

[0042] In the technical solution of this application embodiment, the elastic component 34 is compressed and disposed between the carrier 32 and the linear drive element 33, which can provide a buffering effect between the linear drive element 33 and the carrier 32, avoiding hard contact between the linear drive element 33 and the carrier 32. In addition, by setting the elastic component 34 composed of multiple pressure springs, the change of tension force can be made more gradual (when the band saw 23 is stretched as the usage time increases, if the linear drive element 33 does not stretch, the tension force drops sharply; after setting the elastic component 34, the pressure springs can stretch as the band saw 23 deforms, thereby reducing the magnitude of the tension force drop and making the change of tension force more gradual).

[0043] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the tensioning component 3 further includes a detection component 35, which includes a strain sensor 351 and a display screen 352. The strain sensor 351 is disposed between the elastic component 34 and the linear drive element 33 for detecting pressure. The display screen 352 is disposed on the machine head 12, above the control buttons, and connected to the strain sensor 351 for displaying the pressure value in real time.

[0044] For example, the strain gauge of the strain sensor 351 can be attached to the linear drive element 33 and in contact with the elastic component 34 to detect the pressure value under the compression of the elastic component 34.

[0045] The tension of the food cutting device is not adjusted in real time during use, but rather once after a period of use when the cutting quality is unsatisfactory. The adjustment of tension is affected by subjective factors.

[0046] In the technical solution of this application embodiment, the strain sensor 351 of the detection component 35 can detect the pressure value in real time, and the display screen 352 can display the pressure value in real time, which can provide a reference for the user, so that the tension can be adjusted in time after the pressure value drops to the threshold, making the adjustment of the tension more standardized.

[0047] It is worth noting that the pressure threshold is related to the specifications of the food cutting device; the larger the food cutting device, the higher the threshold. The standard for the threshold can be the minimum available tension minus the weight of the bearing component 32 and the driven wheel 22.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments of this application, an adjustment component 4 is also included. The adjustment component 4 includes a sliding sleeve 41, a support member 42, and an adjustment rod 43. The sliding sleeve 41 is slidably engaged with the bearing member 32 and connected to the driven wheel 22. The support member 42 is disposed on the bearing member 32. The adjustment rod 43 is rotatably disposed on the support member 42 and threadedly connected to the sliding sleeve 41. The axis of the adjustment rod 43 is parallel to the axis of the driven wheel 22 and is used to adjust the position of the driven wheel 22 along the axial direction of the driven wheel 22.

[0049] When adjusting the tension of the food cutting device, the vertical positional relationship between the drive wheel 21 and the driven wheel 22 affects the cutting quality. When there is a vertical deviation between the drive wheel 21 and the driven wheel 22, the band saw 23 will be twisted and deformed in the horizontal direction. This can affect the cutting quality or even cause the band saw 23 to break. Preferably, both the drive wheel 21 and the driven wheel 22 are aligned with the same vertical plane, so that the band saw 23 has no horizontal twisting and deformation, allowing the band saw 23 to be in its optimal state.

[0050] When adjusting the tension, the driven wheel 22 has a vertical displacement. Under this premise, keeping the driving wheel 21 and the driven wheel 22 aligned at all times requires extremely high guiding accuracy from the guide component 31, which not only increases the processing cost but also affects the smoothness of tension adjustment.

[0051] In the technical solution of this application embodiment, the support member 42 can be fixedly installed on the carrier member 32 by bolt fastening. When the adjusting rod 43 is rotated, the threaded connection length between the adjusting rod 43 and the sliding sleeve 41 changes, thereby allowing the driven wheel 22 to translate along its own axis, which facilitates the alignment of the driven wheel 22 with the driving wheel 21. Furthermore, the introduction of the adjusting component 4 reduces the guiding accuracy requirements of the guide member 31, thereby reducing the fitting accuracy between the guide member 31 and the carrier member 32 (the guide member 31 and the carrier member 32 can be a clearance fit), reducing processing costs, and making the adjustment of tension smoother.

[0052] Preferably, when the driven wheel 22 is connected to the sliding sleeve 41, the driven wheel 22 is inserted into the sliding sleeve 41 through its own axle, and its own axis coincides with the axis of the sliding sleeve 41. A bearing is installed between the axle and the sliding sleeve 41, and the driven wheel 22 and the sliding sleeve 41 are rotatably connected through the bearing.

[0053] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the adjusting assembly 4 further includes a fastening nut 44, which is threadedly connected to the adjusting rod 43 and abuts against the machine head 12 to fix the adjusting rod 43.

[0054] For example, the adjusting rod 43 can be a threaded rod, with one end threadedly connected to the sliding sleeve 41 and the other end extending out of the machine head 12, allowing the user to adjust the axial position of the driven wheel 22 from outside the machine head 12. The fastening nut 44 is mounted on the threaded rod and abuts against the side wall of the machine head 12 outside the machine head 12.

[0055] When adjusting the axial position of the driven wheel 22, first loosen the fastening nut 44, then turn the adjusting rod 43 to make the driven wheel 22 move horizontally. After the adjustment is completed, tighten the fastening nut 44 so that the fastening nut 44 abuts against the machine head 12.

[0056] In the technical solution of this application embodiment, the adjusting component 4 can prevent the adjusting rod 43 from rotating due to the vibration of the food cutting machine by setting a fastening nut 44 on the adjusting rod 43, thereby improving the reliability of the adjusting rod 43 and ensuring the axial positional accuracy of the driven wheel 22.

[0057] like Figure 5 As shown, in some embodiments of this application, the sliding sleeve 41 is annular, and the carrier 32 is provided with a carrier hole. The carrier hole is a circular hole, and its axis is parallel to the cutting table surface 111. The carrier hole and the sliding sleeve 41 are slidably engaged.

[0058] For example, the sliding sleeve 41 can be machined as a whole for easy processing, and the bearing hole can be machined by boring.

[0059] In the technical solution of this application embodiment, the sliding sleeve 41 is annular, which not only facilitates processing but also reduces manufacturing costs. The bearing hole is a circular hole, which not only facilitates processing but also improves dimensional accuracy (a circular hole is easier to process than a rectangular hole, which is difficult to process due to its four corners). In addition, when the bearing hole and the sliding sleeve 41 slide together, the mating surfaces are both circular, which can avoid stress concentration and make the fit between the bearing member 32 and the sliding sleeve 41 more reliable.

[0060] like Figure 5 As shown, in some embodiments of this application, the carrier 32 is provided with an upper keyway, the sliding sleeve 41 is provided with a lower keyway, and a guide key is provided between the upper keyway and the lower keyway. The guide key is fixedly connected to the upper keyway and slidably engaged with the lower keyway.

[0061] When the sliding sleeve 41 is annular, it has the advantages of convenient processing and reliable fit. However, it also brings new problems, namely, the circular surface cannot prevent rotation during sliding fit, and will apply a load in the radial direction of the adjusting rod 43.

[0062] In the technical solution of this application embodiment, the guide key is interference-fitted with the upper keyway and can be fixed on the upper keyway, while the guide key is slidingly fitted with the lower keyway (clearance fit), which prevents the sliding sleeve 41 from rotating without affecting the smoothness of the sliding sleeve 41.

[0063] Preferably, both the upper and lower keyways can be machined by milling, and the guide key can be a flat key, using standard parts to further reduce costs.

[0064] like Figure 3 As shown, in some embodiments of this application, both the driving wheel 21 and the driven wheel 22 are provided with guide grooves, and the band saw 23 is located in the guide groove. The depth of the guide groove is greater than the thickness of the band saw 23, and the width of the guide groove is greater than the width of the band saw 23.

[0065] In the technical solution of this application embodiment, the depth of the guide groove is greater than the thickness of the band saw 23, which can prevent the band saw 23 from accidentally coming out during sawing and improve safety. The width of the guide groove is greater than the width of the band saw 23, so that the band saw 23 can be adaptively adjusted during use, thereby avoiding twisting in the horizontal direction.

[0066] like Figures 1 to 5 As shown, the food cutting device in the embodiments of this application will be described in detail below:

[0067] Pressing the start / stop button 122 connects the power supply to the power unit. Pressing the first speed button 123 allows the power unit to drive the band saw 23 at one speed via the drive wheel 21. Pressing the second speed button 124 allows the band saw 23 to run at another speed. In an emergency, pressing the emergency stop button 121 cuts off the power to the power unit, immediately stopping operation. The first speed button 123 and the second speed button 124 are optional and are matched to the power unit (motor). When the motor has multiple operating speeds, multiple speed buttons can be set accordingly; when the motor has only one operating speed, one speed button is sufficient.

[0068] When adjusting the tension, the power element stops operating. Pressing the up button 125 causes the linear drive element 33 to push the driven wheel 22 upward; after stopping the press, the linear drive element 33 stops extending and remains in its current state. Pressing the down button 126 causes the linear drive element 33 to push the driven wheel 22 downward; after stopping the press, the linear drive element 33 stops retracting and remains in its current state. During normal operation of the food cutting device and when adjusting the tension, the display screen 352 shows the pressure value in real time. When adjusting the tension, the fastening nut 44 of the adjusting component 4 needs to be loosened.

[0069] When adjusting the axial position of the driven wheel 22, first loosen the fastening nut 44, then twist the adjusting rod 43 to adjust the axial position of the driven wheel 22, and finally tighten the fastening nut 44.

[0070] After adjusting the axial position and / or tension of the driven wheel 22, the driven wheel 22 needs to be manually rotated several times (e.g., at least five times) to allow the band saw 23 to adapt before the sawing operation on the food can begin.

[0071] As is known from common technical knowledge, this application can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this application or equivalent to this application are included in this application.
