[0048] The housing body 10 is provided with a rotating disk 80 and a first small bevel gear 90 which are vertically distributed to each other. The rotating disk 80 is sleeved on one end of the first rotating shaft 40. The screw rod 60 is connected to the first rotating shaft 40 through a first transmission assembly 100. The screw rod 60 is connected to the first small bevel gear 90 through a second transmission assembly 110.

[0049] A shift assembly 120 is provided in the casing body 10. The shift assembly 120 includes a first shift housing 121 fixedly installed in the casing body 10. The first shift housing 121 is provided with a second rotating shaft 122 that is movably connected. A clutch plate 123 and a first large bevel gear 124 are sleeved on one end of the second rotating shaft 122. The clutch plate 123 is used to be engaged with the rotating plate 80. The first large bevel gear 124 is used to be meshed and connected with the first small bevel gear 90. The other end of the second rotating shaft 122 is provided with a driving handle 130 located outside the casing body 10.

[0050] The fruit and vegetable printing machine prints and slices the processed fruits and vegetables in the first working state or the second working state; wherein, in the first working state, the rotating disk 80 is in contact with the clutch disk 123, and the first large bevel gear 124 is not meshed with the first small bevel gear 90; in the second working state, the rotating disk 80 is not in contact with the clutch disk 123, and the first large bevel gear 124 is meshed and connected with the first small bevel gear 90.

[0051] It should be noted that the fruit and vegetable printing machine provided by the present invention drives the spline shaft 50 and the slicing assembly 20 to move through the driving action of the driving handle 130, so that the printing assembly 30 prints the processed fruits and vegetables, and the slicing assembly 20 slices the printed fruits and vegetables; because the gear shift assembly 120 plays a gear shift and speed regulation role, the slicing speed of the slicing assembly 20 can be regulated. Therefore, the fruit and vegetable printing machine provided by the present invention is convenient for synchronous slicing and printing of fruits and vegetables.

[0052] like Figure 12-14 As shown, the shift assembly 120 further includes a shift reed 125 located in the first shift housing 121, one end of the shift reed 125 is connected to the first shift housing 121, and the other end of the shift reed 125 is suspended; the second rotating shaft 122 is movably engaged with the shift reed 125. In this embodiment, a slot 1221 is provided on the second rotating shaft 122.

[0053] It should be noted that when the clutch disc 123 is engaged with the rotating disc 80, the engaging groove 1221 is not in contact with the shifting spring 125; through the driving action of the driving handle 130, the second rotating shaft 122 drives the clutch disc 123 to rotate, so that the clutch disc 123 drives the rotating disc 80 to rotate, and the first main shaft drives the spline shaft 50 to rotate; at the same time, through the transmission action of the first transmission assembly 100, the screw rod 60 drives the slicing assembly 20 to move, thereby realizing the printing and slicing processing;

[0054] When the clutch disk 123 is separated from the rotating disk 80, the second rotating shaft 122 drives the first large bevel gear 124 to rotate through the driving action of the driving handle 130. Since the first large bevel gear drives the first small bevel gear 90 to rotate, the screw rod 60 drives the slicing assembly 20 to move through the transmission action of the second transmission assembly 110. At the same time, through the transmission action of the first transmission assembly 100, the first main shaft drives the spline shaft 50 to rotate, thereby realizing printing and slicing processing.

[0055] like Figure 12-14As shown, the second rotating shaft 122 is sleeved with a return spring 126, and the return spring 126 abuts against the shift spring 125; the shift spring 125 is provided with a button 1251, and the first shift housing 121 is provided with an opening 1211 for accommodating the button 1251; in this embodiment, by pressing the button 1251, the shift spring 125 and the second rotating shaft 122 are released from the clamping, and the clutch plate 123 is reset under the elastic force of the return spring 126, so that the rotating plate 80 is clamped with the clutch plate 123;

[0056] The first shift housing 121 is provided with a second shift housing 127 embedded in the housing body 10 . The second shift housing 127 is provided with a receiving groove 1271 . The button 1251 is located in the receiving groove 1271 .

[0057] like Figure 12-14 As shown, a shift handle 128 is fixedly mounted on the driving handle 130. It should be noted that by pulling the shift handle 128, fast shifting can be achieved.

[0058] like Figure 2 and Fig.15 As shown, the slicing assembly 20 includes a slicing frame 21 fixedly sleeved with the slide 70, and a slicing knife 22 is fixedly mounted on the slicing frame 21. In the specific implementation process, the slicing frame 21 is fastened to the slide 70 by screws, and the slicing knife 22 is fastened to the slicing frame 21 by screws.

[0059] like Figure 2-4 As shown, the printing assembly 30 includes a printing shaft 31 rotatably connected to the housing body 10, one end of the printing shaft 31 is sleeved with a printing frame 32, a printing roller 33 is rotatably connected in the printing frame 32, and printing gears 34 are installed at opposite ends of the printing roller 33. It should be noted that the printing roller is in direct contact with the processed fruits and vegetables. When the spline shaft 50 drives the processed fruits and vegetables to rotate, the printing roller 33 rotates on the printing frame 32 to print the processed fruits and vegetables; different types of printing can be achieved by replacing different printing rollers 33;

[0060] It should also be noted that the size of the printing roller blade 33 and the size of the printing gear 34 can be changed according to the needs, and the depth of printing can be adjusted to adapt to slices of different thicknesses. Fig.16 As shown, the distance between the center line of the printing roller 33 and the center line of the printing shaft 31 is equal to the distance between the center line of the spline shaft 50 and the center line of the printing shaft 31. Through the above-mentioned specific corresponding relationship, it can be ensured that the pattern of each slicing and printing of fruits and vegetables will not be deformed or distorted.

[0061] like Figure 2-4As shown, a printing handle 35 is fixedly mounted on one end of the printing frame 32, and a reset ball head 36 is provided at one end of the printing shaft 31 located in the housing body 10; an isolation sleeve 37 is sleeved on the printing shaft 31, and the isolation sleeve 37 is respectively in contact with the housing body 10 and the printing frame 32. In the specific implementation process, the isolation sleeve 37 and the printing shaft 31 can be threadedly connected, and the reset ball head 36 has a specific elastic force. By setting the reset ball head 36, the printing shaft can be prevented from falling off from the housing body 10.

[0062] like Figure 2 , Figure 5 and Figure 6 As shown, the housing body 10 includes a first outer shell 11 and a second outer shell 12 that are mutually engaged, an inner shell 13 is installed between the first outer shell 11 and the second outer shell 12, and a supporting foot 14 that passes through the first outer shell 11 is fixedly connected to the inner shell 13. In a specific implementation process, the inner shell 13 is fixedly installed in the first outer shell 11, the first outer shell 11 is provided with a first opening 111, and the inner shell 13 is provided with a second opening 131 corresponding to the first opening 111, and the first opening 111 and the second opening 131 are used to accommodate the linear movement of the slide seat 70.

[0063] It should be noted that the number of support legs 14 is set to four, and the support legs 14 include a mounting base 141, a support rod 142 and a support base 143 which are arranged in sequence. One end of the support rod 142 passes through the first outer shell 11 and is fixedly connected to the mounting base 141, and the other end of the support rod 142 is hinged to the support base 143, and the mounting base 141 is fixedly installed in the inner shell 13.

[0064] like Figure 7-11 As shown, the first transmission assembly 100 includes a second small bevel gear 101 sleeved with the first rotating shaft 40, and one end of the screw rod 60 is sleeved with a second large bevel gear 102 meshing with the second small bevel gear 101. It should be noted that through the meshing of the second small bevel gear 101 and the second large bevel gear 102, the transmission can be better realized, and the rotation speed of the spline shaft 50 can be adjusted.

[0065] like Figure 7-11 As shown, the second transmission assembly 110 includes a large spur gear 111 coaxially rotating with the first small bevel gear 90, and a third rotating shaft 112 is rotatably connected in the housing body 10, and a small spur gear 113 meshing with the large spur gear 111 is sleeved on one end of the third rotating shaft 112;

[0066] The other end of the third rotating shaft 112 is sleeved with a first synchronous wheel 114, and one end of the screw rod 60 is sleeved with a second synchronous wheel 115 corresponding to the first synchronous wheel 114. The first synchronous wheel 114 and the second synchronous wheel 115 are connected by a belt 116. It should be noted that the rotation speed of the spline shaft 50 can be changed by the configuration of the second transmission assembly 110.

[0067] Working principle: When the working gear of the fruit and vegetable printing machine is in the slow-in and slow-out state, the processed fruits and vegetables are sliced ​​thinly. When the clutch disk 123 is engaged with the rotating disk 80, the slot 1221 is not in contact with the shift spring 125; through the driving action of the driving handle 130, the second rotating shaft 122 drives the clutch disk 123 to rotate, so that the clutch disk 123 drives the rotating disk 80 to rotate, and the first main shaft drives the spline shaft 50 to rotate; at the same time, through the transmission action of the first transmission assembly 100, the second small bevel gear 101 drives the second large bevel gear 102 to rotate, so that the screw rod 60 drives the slicing assembly 20 to move, thereby realizing the thin slicing of fruits and vegetables;

[0068] When the working gear of the fruit and vegetable printing machine is in the fast-in and fast-out position, the processed fruits and vegetables are cut into thick slices. Through the shifting of the shifting assembly 120, the clutch disc 123 is separated from the rotating disc 80. Through the driving action of the driving handle 130, the second rotating shaft 122 drives the first large bevel gear 124 to rotate. Since the first large bevel gear drives the first small bevel gear 90 to rotate, through the transmission action of the second transmission assembly 110, the screw rod 60 drives the slicing assembly 20 to move. At the same time, through the transmission action of the first transmission assembly 100, the second large bevel gear 102 drives the second small bevel gear 101 to rotate, so that the first main shaft drives the spline shaft 50 to rotate, thereby realizing the thick slicing of fruits and vegetables.

[0069] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
