[0002] In the catering industry and household scenarios, fruit and vegetable processing equipment is a relatively common processing equipment. Fruit and vegetable processing equipment has a rotatable cutter disc with blades on it. Currently, there is a type of fruit and vegetable processing equipment on the market in which the blades of the cutter disc are an integrated structure with the disc body. However, the production cost of the blades with this integrated structure is relatively high, and the sharpness and wear resistance of the blades are limited, which is not as good as split blade products. Moreover, after long-term use, the blades will be severely worn, which will affect the processing effect and efficiency of fruits and vegetables, and thus affect the user experience. In addition, since the blades on the cutter disc are an integrated structure, after long-term use, due to blade wear / damage, the entire cutter disc assembly needs to be replaced, which wastes resources and is not conducive to energy conservation and emission reduction.

[0042] Example 1

[0043] A specific embodiment of the present invention is as follows Figures 1 to 6As shown, a cutter disc for fruit and vegetable processing equipment is disclosed, hereinafter referred to as cutter disc 100, comprising a disc body 101, a blade 102 and a locking piece 103. A mounting groove 1012 is provided on the disc body 101, and the blade 102 is fixed in the mounting groove 1012 by the locking piece 103. The cutting edge of the blade 102 is higher than the upper surface of the disc body 101.

[0044] In this embodiment, there is at least one blade 102, and the number of mounting slots 1012 on the disc 101 matches the number of blades 102. The blades 102 can be arranged on the disc 101 at geometrically even angles, or at geometrically uneven angles and asymmetrically offset positions. The arrangement of the blades 102 ensures that when the disc 101 rotates, the fruit to be peeled is thrown upward and diagonally, colliding with the blades 102, thereby cutting the peel of the fruit.

[0045] In this embodiment, the shape of the mounting groove 1012 on the disk body 101 is adapted to the shape of the blade 102, that is, the blade 102 follows the contour of the mounting groove 1012 of the disk body 101. When the blade 102 is installed in the mounting groove 1012, the position of the blade 102 is accurately positioned.

[0046] In this embodiment, a mounting through hole 1021 is provided on the blade 102 , and the locking member 103 passes through the mounting through hole 1021 to fix the blade 102 on the disk body 101 .

[0047] In this embodiment, the locking member 103 includes but is not limited to the following three structures:

[0048] The first locking member 103 structure is as follows: Figure 4As shown, the locking member 103 is a rivet 1031 having a head, a body, and a tail. The blade 102 is fixed to the disk body 101 by riveting 1031. Specifically, the bottom surface of the mounting slot 1012 on the disk body 101 is provided with a rivet hole that matches the size of the rivet 1031. After the blade 102 is installed in the mounting slot 1012, the mounting through-hole 1021 on the blade 102 is aligned with the rivet hole, and the blade 102 is fixed in the mounting slot 1012 by the rivet 1031. The top openings of the mounting through-hole 1021 and the rivet hole are outwardly expanded. It can also be understood that the mounting through-hole 1021 on the blade 102 is a first reduced diameter hole, the upper portion of the rivet hole is a second reduced diameter hole, and the lower portion of the rivet hole is a regular cylindrical hole, the aperture diameter of the cylindrical hole being equal to the aperture diameter of the small hole of the reduced diameter hole. After the blade 102 is installed in the mounting groove 1012, the hole wall of the first reduced diameter hole and the hole wall of the second reduced diameter hole are coplanar, that is, the first reduced diameter hole and the second reduced diameter hole are aligned to form a larger combined reduced diameter hole. The shape of the lower end face of the head of the rivet 1031 is adapted to the hole wall shape of the combined reduced diameter hole, and the head profile is contoured with the aperture profile of the blade 102 installation through hole 1021. After the rivet 1031 rivets the blade 102, the head of the rivet 1031 is located in the combined reduced diameter hole, the top of the head of the rivet 1031 is flush with the top surface of the blade 102 or is located below the top surface of the blade 102, and the lower end face of the head is in surface contact with the hole wall surface of the combined reduced diameter hole, which can provide sufficient supporting force and area so that the rivet 1031 can fully compact the hole wall surface of the combined reduced diameter hole. The tail is the reinforced part of the rivet 1031. When the compression force acts on the rivet 1031, the air between the head and the tail is squeezed out, and the tail expands and turns over to form a close contact with the lower surface of the disk body 101, thereby realizing the riveted connection of the locking blade 102.

[0049] The second locking member 103 structure is as follows: Figure 5As shown, the locking element 103 is a screw 1032 having a cap and a shank. The bottom surface of the mounting slot 1012 on the disk body 101 is provided with a threaded mounting hole. After the blade 102 is installed in the mounting slot 1012, the screw 1032 is inserted through the mounting hole 1021 of the blade 102 to secure the blade 102 within the mounting slot 1012. The threaded mounting hole differs from the aforementioned rivet hole in that the lower portion of the threaded mounting hole is a threaded hole that matches the size of the screw 1032. The mounting hole 1021 on the blade 102 is a first reduced diameter hole, the upper portion of the threaded mounting hole is a second reduced diameter hole, and the lower portion of the threaded mounting hole is a regular threaded hole. When the blade 102 is installed in the mounting slot 1012, the wall of the first reduced diameter hole is coplanar with the wall of the second reduced diameter hole, i.e., the first and second reduced diameter holes are aligned to form a larger combined reduced diameter hole. The shape of the lower end face of the cap matches the shape of the wall of the combined reduced diameter hole, and the profile of the cap aligns with the opening profile of the through hole 1021 for mounting the blade 102. When the screw 1032 secures the blade 102 to the disk body 101, the cap of the screw 1032 is located within the combined reduced diameter hole, with the top of the cap flush with or below the top surface of the blade 102, and the lower end face of the cap in surface contact with the wall of the combined reduced diameter hole. This provides sufficient support force and area, allowing the cap to fully compact the wall of the combined reduced diameter hole, thereby locking and correcting the position of the blade 102 through the pressing force of the screw 1032 and the cap's external structure. In the solution using the screw 1032 to secure the blade 102, if the blade 102 becomes defective, it can be replaced at any time, making disassembly and assembly convenient and quick, and saving manufacturing and use costs.

[0050] The third locking member 103 structure is as follows: Figure 6 As shown, locking member 103 is integrally molded with disk body 101. Locking member 103 is made of a plastically deformable material. Through a press riveting or hot riveting process, the head of locking member 103 is flanged to lock blade 102. Specifically, locking member 103 is a press rivet 1033 that protrudes from the bottom surface of mounting slot 1012 on disk body 101. Press rivet 1033 is a cylindrical structure, and the number and position of the cylindrical structures correspond to the number and position of mounting holes 1021 on blade 102. Press rivet 1033 is integrally formed on the bottom surface of mounting slot 1012. When the blade 102 is installed in the mounting groove 1012, the rivet 1033 passes through the mounting hole 1021 of the blade 102 from bottom to top. A gap exists between the top of the rivet 1033 and the first reduced diameter hole wall of the mounting hole 1021. Under external pressure or external pressure combined with heating, the top of the rivet undergoes plastic deformation and squeezes into the gap between the rivet and the first reduced diameter hole wall, thereby achieving a reliable connection between the blade 102 and the disk body 101. Figure 6 , the flattened rivet 1033a and the rivet 1033 before being flattened.

[0051] Since the blade of the existing food processing equipment is connected to the drive shaft, it is difficult to control the tightness of the drive shaft and the shaft sleeve on the blade, which can easily lead to the blade being too loose or too tight. When it is too loose, the blade will shake on the shaft, the blade will rotate unsteadily, and there will be a lot of noise. When it is too tight, the user has to use a lot of force to insert and remove the blade, which is very inconvenient. Based on this, in this embodiment, the blade 100 and the drive shaft 401 of the host 400 can be quickly assembled. Figures 7 to 10 As shown, a center sleeve 1011 is provided at the center of the cutter head 100, which protrudes upward. The axial lower end of the center sleeve 1011 is opened; the axial upper end of the center sleeve 1011 is opened or blind-hole-set. The center sleeve 1011 is divided into three sections to cooperate with the drive shaft 401. Among the three matching sections of the center sleeve 1011 and the drive shaft 401, the upper one is the upper matching section 1011A, the lower one is the lower matching section 1011B, and the middle one is the middle matching section. 1011C; the drive shaft 401 includes an upper shaft section 401a corresponding to the upper mating section 1011A, a lower shaft section 401b corresponding to the lower mating section 1011B, and a middle shaft section 401c corresponding to the middle mating section 1011C. A gap exists between at least the middle mating section 1011C and the middle shaft section 401c. At least one of the upper mating section 1011A and the lower mating section 1011B is provided with a circumferential positioning structure to enable the cutter disc to rotate when the drive shaft 401 rotates. When the cutter disc's center bushing 1011 is fitted onto the drive shaft 401, the upper mating section 1011A and the lower mating section 1011B cooperate to allow the cutter disc to stably rotate with the drive shaft 401.

[0052] For example, a circumferential positioning structure is provided on the upper mating section 1011A. Optionally, the circumferential positioning structure can be a combination of one or more structures with a circumferential drive structure, such as a keyway, a regular polygon, or a circumferentially flat position. Exemplarily, the upper mating section 1011A adopts a circumferentially flat position structure to transmit rotational power. Specifically, the upper mating section 1011A of the drive shaft 401 is configured as a cylinder, and two flat positions 401g are provided on the cylinder. The two flat positions 401g cooperate with the two flat positions of the center sleeve 1011 to transmit rotational power.

[0053] The average diameter of the drive shaft 401 in the upper mating section 1011A is Da, the average diameter of the drive shaft 401 in the lower mating section 1011B is Db, and the average diameter of the drive shaft 401 in the middle mating section 1011C is Dc. Thus, Da ≤ Dc < Db. The average diameters Da, Db, and Dc refer to the average values ​​of the radial widths in a broad sense and are not limited to the diameters of a circle in a narrow sense.

[0054] The clearance between the upper fitting section 1011A and the upper shaft 401a is Sa, the clearance between the lower fitting section 1011B and the lower shaft 401b is Sb, and the clearance between the middle fitting section 1011C and the middle shaft 401c is Sc. Then Sa <Sc,Sb<Sc。

[0055] The clearances Sa, Sb, and Sc can be positive or negative. When they are positive, it means there is a clearance in the fit; when they are negative, it means there is an interference fit.

[0056] The transition between the three mating sections of the inner surface of the center sleeve 1011 can be a stepped transition or a smooth transition. In accordance with the inner surface structure of the center sleeve 1011, the transition between the three mating sections of the outer surface of the drive shaft 401 can be a stepped transition or a smooth transition.

[0057] For example, the inner surface of the center sleeve 1011 has an inclined and smooth transition between the inner surfaces of the upper mating section 1011A and the middle mating section 1011C, and a step transition is used between the inner surfaces of the middle mating section 1011C and the lower mating section 1011B; the outer surface of the drive shaft 401 has a smooth transition of the same shape between the outer surfaces of the upper shaft 401a and the middle shaft 401c, and a step transition is used between the outer surfaces of the middle shaft 401c and the lower shaft 401b.

[0058] Reference Figure 9 The outer surfaces of the upper shaft 401a and the middle shaft 401c are coplanar and smooth; the connection between the lower shaft 401b and the middle shaft 401c has an annular stepped end surface 401h, and the connection between the inner wall surface of the middle matching section 1011C and the lower matching section 1011B has a stepped matching surface. When the drive shaft 401 is installed in the center sleeve 1011, the upper shaft 401a and the top sleeve of the upper matching section 1011A have a first contact point 401d, and the middle section The shaft 401c does not contact the inner wall of the middle mating section 1011C, the lower section shaft 401b has a second contact point 401e with the bottom end sleeve of the lower mating section 1011B, and the annular stepped end surface 401h of the lower section shaft 401b has a third contact point 401f with the stepped mating surface of the inner wall of the center sleeve 1011; the gap Sc is located between the first contact point 401d and the third contact point 401f, and the gap Sa is located above the gap Sb.

[0059] This embodiment also discloses a fruit and vegetable processing device, including the above-mentioned cutter head 100 and a main unit 400, a peel box 200 and a feed barrel 300. Figures 11 to 15As shown, the peel box 200 can be detachably mounted on the main unit 400, and the discharge barrel 300 can be detachably mounted on the peel box 200; the fruits and vegetables added to the discharge barrel 300 enter the peel box 200 under the action of the automatic discharge mechanism and are peeled in the peel box 200.

[0060] In one optional embodiment, a feeding barrel 300 includes a barrel body 301, with an upwardly open top and a feeding port 302 at the bottom. An automatic feeding mechanism 303 is disposed within the barrel body 301. Disturbing ribs 304 are fixedly disposed below the bottom of the barrel body 301. The inner walls of the ribs 304 define a disturbance space, which serves as a processing space for fruits and vegetables that enter the disturbance space through the feeding port 302. A fruit and vegetable outlet 305 is disposed on one side of the ribs 304. After processing within the disturbance space created by the ribs 304, the fruits and vegetables are discharged from the fruit and vegetable outlet 305.

[0061] In one optional embodiment, the fruit peel box 200 includes a box body 201, in which a knife disc 100 and a spoiler 202 are arranged; the knife disc 100 is rotatably arranged in the box body 201, and the spoiler 202 is arranged above the knife disc 100, and a processing space for fruits and vegetables is formed between the inner side surface of the spoiler 202 and the top surface of the knife disc 100.

[0062] Compared with the prior art, the cutter disc for fruit and vegetable processing equipment and the fruit and vegetable processing equipment provided in this embodiment have at least one of the following beneficial effects:

[0063] 1. The blade is locked by a locking mechanism, so you can choose blades already on the market, which not only reduces the cost of the cutter head, but also reduces the production scrap rate, reduces customer use costs, and is energy-saving and environmentally friendly.

[0064] 2. The blade can be replaced. For example, when using screw installation, the blade can be quickly replaced by screwing the screw. It is convenient and fast, effectively prolonging the service life of the cutter disc, saving customers' use costs, and reducing waste of resources.

[0065] 3. The center sleeve of the cutter disc and the shaft adopt a three-section matching connection method. While reducing the matching area, the matching length is lengthened, the difficulty of parts manufacturing is reduced, and the stability of the cutter disc rotation is ensured. Due to the large matching clearance of the middle matching section, the friction is small during assembly and disassembly, which is very convenient to operate and convenient for users to assemble and disassemble quickly.

[0066] 4. By fixing the spoiler rib at the bottom of the barrel, users only need to install and disassemble one part during installation, use, and cleaning, which is very convenient and also eliminates the risk of losing or missing the spoiler rib.

[0067] 5. By setting the spoiler ring above the knife disc, fruits and vegetables can contact the blade regardless of whether there are raised positions in the spoiler ring, which greatly improves the efficiency of fruit and vegetable processing, and the fruit and vegetable skin is cut evenly, with significantly improved results.

[0068] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of this application. It should be understood that the above description is only the specific implementation methods of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
