Description

Technical Field

[0001] The present invention relates to the technical field of food processing machinery, and particularly relates to an efficient dicing machine. Background Art

[0002] Dicing machines are commonly used to cut edible crops such as fruits and vegetables into dices during deep processing, and are widely used in dehydrated vegetables, quick-frozen vegetable processing plants, soft ingredients such as jelly and herbal jelly, and the food pickles industry. Currently, for dicing fruits and vegetables, the roller cutting method is generally adopted. The dicing component is composed of a slicing knife and a round cutting knife. During operation, the material makes a centrifugal motion through a high-speed rotating guide plate. The centrifugal force makes the material rotate closely against the side wall of the guide cylinder. There are strip-shaped cutting openings on the side wall of the guide cylinder. The part of the material extending out of the cutting opening passes through the slicing knife and the round cutting knife in sequence to be cut into dices.

[0003] For the existing dicing machines, since the size of the cutting opening is fixed at a certain position, it is difficult to adjust the size of the cutting opening to change the cutting thickness of the slicing knife on the material, and thus it is difficult to adjust the overall thickness of the material according to actual needs, resulting in low practicality. Summary of the Invention

[0004] Aiming at the deficiencies existing in the prior art, one of the purposes of the present invention is to provide an efficient dicing machine, which can adjust the size of the cutting opening, so that products with different thicknesses can be cut according to requirements.

[0005] The above invention purpose of the present invention is achieved through the following technical solutions:

[0006] An efficient dicing machine includes a machine body. The machine body is provided with a feeding part, a cutting part and a discharging part. The feeding part includes a guide cylinder and a pusher rotatably arranged inside the guide cylinder. The pusher is provided with a plurality of guide plates. A cutting opening is formed on the side wall of the guide cylinder. The guide cylinder includes a cylinder base and an upper cover. One side of the cylinder base and the upper cover are rotatably connected to each other. The other sides of the cylinder base and the upper cover are respectively located on both sides of the cutting opening. The cutting part is located on one side of the cutting opening. An elevating rod is rotatably arranged on the upper cover. The elevating rod is provided with an adjusting mechanism for adjusting the size of the cutting opening. The elevating rod is fixed to the cylinder base through a fixing mechanism.

[0007] By adopting the above technical solutions, the pusher rotates at a high speed, and the guide plates drive the material to rotate at a high speed. The material is attached to the side wall of the guide cylinder under the action of centrifugal force. When the material passes through the cutting opening position, it extends out of the side wall of the guide cylinder. The cutting part cuts the material at the cutting opening position, and then discharges it through the discharging part. One side of the upper cover is rotatably connected to the cylinder base. By driving the upper cover to flip around its connection point with the cylinder base through the adjusting structure, the distance between the end of the upper cover close to the cutting opening and the cutting part is changed, and the height difference between the cutting part and the upper cover is changed. Thus, the material can be cut into different thicknesses according to requirements, improving practicality.

[0008] In a preferred embodiment of the present invention, it can be further configured that: the adjusting mechanism includes a support rod and a screw rod. The support rod is rotatably arranged on the barrel base and is located above the lifting rod. The screw rod is rotatably arranged on the support rod. The lifting rod is provided with a threaded hole, and the screw rod passes through the threaded hole.

[0009] By adopting the above technical solution, rotating the screw rod can drive the lifting rod to move on the screw rod. Since the lifting rod is rotatably connected to the upper cover and the support rod is rotatably connected to the barrel base, the upper cover can be flipped around its rotation connection point with the barrel base, the distance between the upper cover and the cutting part can be adjusted, thereby changing the height difference between the upper cover and the cutting part, adjusting the size of the cutting opening, and thus the cutting thickness of the material can be adjusted.

[0010] In a preferred embodiment of the present invention, it can be further configured that: the adjusting mechanism includes a worm gear, a worm, two gears and two arc-shaped racks. The two gears are fixedly arranged at both ends of the lifting rod. The two arc-shaped racks are fixedly arranged on both sides of the top of the barrel base. The center position of the arc-shaped rack coincides with the rotation connection point of the upper cover and the barrel base. The gears are meshed with the arc-shaped racks. The worm gear is fixedly arranged on the lifting rod. The worm is rotatably arranged on the upper cover body. The worm is meshed with the worm gear.

[0011] By adopting the above technical solution, rotating the worm drives the worm gear and the lifting rod to rotate synchronously, drives the gear to rotate around the arc-shaped rack, and drives the upper cover to flip around its rotation connection point with the barrel base, the distance between the upper cover and the cutting part can be adjusted, thereby changing the size of the cutting opening, and the cutting thickness of the material can be adjusted according to needs.

[0012] In a preferred embodiment of the present invention, it can be further configured that: the fixing mechanism is set as a fastening nut. The barrel base is provided with an arc-shaped hole on one side of the lifting rod. The center position of the arc-shaped hole coincides with the rotation connection point of the upper cover and the barrel base. One end of the lifting rod passes through the arc-shaped hole and is threadedly connected to the fastening nut.

[0013] By adopting the above technical solution, the lifting rod slides inside the arc-shaped hole through the adjusting structure, tightens the fastening nut on the side wall of the barrel base, makes the fastening nut tightly abut against the barrel base, fixes the lifting rod and the barrel base to each other, and fixes the barrel base and the upper cover to each other, avoiding the upper cover from moving during the cutting process.

[0014] In a preferred embodiment, the present invention can be further configured as follows: the feeding section, the cutting section, and the discharging section are all covered with machine covers. The guide tube is provided with a feeding port, and the machine cover is provided with a feeding hopper communicating with the feeding port. On the opposite inner sidewalls of the feeding hopper, limiting plates are rotatably arranged. On the side where the two limiting plates are close to each other, a push rod is rotatably arranged. At the end of the push rod away from the limiting plate, a sliding rod is rotatably arranged. On the opposite sidewalls of the feeding hopper, sliding holes are opened. The end of the sliding rod away from the push rod passes through the sliding hole and is connected to a driving member.

[0015] By adopting the above technical solution, the driving member is used to push the sliding rod to slide inside the sliding hole. During the movement of the sliding rod, the push rod is pushed to support the limiting plate. When the sliding rod moves to the position at one end of the sliding hole close to the limiting plate, the two limiting plates are close to each other and in a closed state, which can intercept the materials inside the feeding hopper from entering the guide passage through the feeding port. When the sliding rod moves to the position at one end of the sliding hole away from the limiting plate, the two limiting plates are away from each other and in an unfolded state, and the materials can enter the guide tube through the feeding port. By adjusting the unfolded and closed states of the limiting plate, the flow rate of the materials in the feeding hopper can be limited, avoiding excessive materials from blocking the feeding port.

[0016] In a preferred embodiment, the present invention can be further configured as follows: the cutting section includes a slicing knife and a circular cutting knife seat. On the side of the mounting plate close to the cylinder seat, a slot is opened. The slicing knife is inserted into the slot. The cutting edge of the slicing knife is located at the cutting opening and is tangent to the outer peripheral wall of the guide tube. At one end of the cutting knife extending out of the slot, a disassembly and assembly hole is opened.

[0017] By adopting the above technical solution, the slicing knife is clamped inside the slot of the mounting plate. When disassembly is required, the staff uses a tool to pass through the disassembly and assembly hole and pull out the slicing knife, which is convenient for cleaning the slicing knife.

[0018] In a preferred embodiment, the present invention can be further configured as follows: the circular cutting knife seat is rotatably provided with a plurality of circular cutting knives through a rotating shaft. The end of the rotating shaft extends out of the side wall of the circular cutting knife seat. The mounting plate is provided with two insertion posts. The circular cutting knife seat is provided with two mounting holes. The insertion posts pass through the mounting holes and are connected with fastening members. The machine body is rotatably provided with a core shaft connected to the driving device. The rotating shaft is provided with a square clamping block, and a square groove for clamping with the square clamping block is opened on the side wall of the core shaft.

[0019] By adopting the above technical solution, the circular cutting knife seat is detachably arranged on the mounting plate. The insertion posts are inserted into the mounting holes, and the fastening members are tightened to fix the circular cutting knife seat on the mounting plate. The square clamping block and the square groove are clamped with each other, so that the core shaft can drive the rotating shaft to rotate synchronously, and the circular cutting knives rotate to cut the materials. The circular cutting knife seat is detachably fixed on the mounting plate, which is convenient for disassembling and cleaning the circular cutting knife seat.

[0020] In a preferred embodiment, the present invention can be further configured as follows: the discharging part includes a chopping knife cylinder located on one side of the circular cutting knife seat and a blanking plate located below the chopping knife cylinder. A pin shaft is rotatably arranged on the machine body. The pin shaft is connected with an auxiliary support shaft through a flange plate. The auxiliary support shaft penetrates through the chopping knife cylinder. A positioning block with a hexagonal cross-section is arranged on the side wall of the auxiliary support shaft. The positioning block is cooperatively inserted with the inner wall of the chopping knife cylinder. One end of the auxiliary support shaft passing through the chopping knife cylinder is connected with a locking member.

[0021] By adopting the above technical solution, the rotation of the pin shaft drives the rotation of the auxiliary support shaft. The positioning block is cooperatively clamped with the chopping knife cylinder, and the auxiliary support shaft can drive the chopping knife cylinder to rotate synchronously. When the auxiliary support shaft is bent or broken, the locking member is removed, and the chopping knife cylinder is disengaged from the auxiliary support shaft. The auxiliary support shaft and the pin shaft are connected through a flange plate. By removing the flange plate, the auxiliary support shaft can be replaced, which is convenient for maintenance and reduces the maintenance cost.

[0022] In a preferred embodiment, the present invention can be further configured as follows: an indicating line is opened at one end of the rotating shaft away from the square clamping block, and an alignment line coinciding with the extension line of the indicating line is opened on the circular cutting knife seat.

[0023] By adopting the above technical solution, the rotation of the rotating shaft drives the rotation of the core shaft. When the indicating line coincides with the extension line of the alignment line, the circular cutting knife seat can move along the length direction of the insertion post, so that the square clamping block can be disengaged from or engaged with the square groove, which is convenient for the staff to disassemble and assemble the circular cutting knife seat.

[0024] In a preferred embodiment, the present invention can be further configured as follows: the sliding rod is provided with a baffle for blocking the sliding hole, and the baffle is located outside the feed hopper.

[0025] By adopting the above technical solution, the sliding rod slides inside the sliding hole, which can drive the limiting plate to flip. The baffle always blocks the sliding hole, preventing the material inside the feed hopper from running out from the position of the sliding hole.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects:

[0027] 1. The propeller rotates at a high speed, and the material guide plate drives the material to rotate at a high speed. The material is attached to the side wall of the material guide cylinder under the action of centrifugal force. When the material passes through the cutting port position, it extends out of the side wall of the material guide cylinder. The cutting part cuts the material at the cutting port position, and then discharges it through the discharging part. The upper cover is rotatably connected to one side of the cylinder seat. By driving the upper cover to flip around the connection point with the cylinder seat through the adjustment structure, the distance between the end of the upper cover close to the cutting port and the cutting part is changed, which can change the height difference between the upper cover and the cutting part and adjust the size of the cutting port. Thus, the material can be cut into different thicknesses according to requirements, improving the practicability;

[0028] 2. Rotating the screw rod can drive the lifting rod to move on the screw rod. Since the lifting rod is rotatably connected to the upper cover and the support rod is rotatably connected to the cylinder base, the upper cover can be flipped around its rotation connection point with the cylinder base, the distance between the upper cover and the cutting part can be adjusted, thereby adjusting the size of the cutting opening, and thus the cutting thickness of the material can be adjusted;

[0029] 3. Rotating the worm drives the worm wheel and the lifting rod to rotate synchronously, drives the gear to rotate around the arc-shaped rack, and drives the upper cover to flip around its rotation connection point with the cylinder base. The distance between the upper cover and the cutting part can be adjusted, thereby changing the size of the cutting opening, and the cutting thickness of the material can be adjusted as needed.

Detailed implementation mode

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Embodiment 1

[0040] Refer to Figure 1 、 Figure 2 and Figure 3 , a highly efficient dicing machine disclosed by the present invention, includes a machine body 1. A feeding part, a cutting part and a discharging part are installed on one side of the machine body 1. The feeding part includes a cylindrical material guiding cylinder 2 and a pusher 24. The material guiding cylinder 2 is fixed on the side wall of the machine body 1. A feed inlet 25 is opened on the side of the material guiding cylinder 2 facing away from the machine body 1. The pusher 24 is rotatably installed inside the material guiding cylinder 2. A strip-shaped cutting opening 23 is opened on the side wall of the material guiding cylinder 2. The cutting part includes a slicing knife 6 and a circular cutting knife seat 4 installed in sequence on one side of the cutting opening 23. A plurality of circular cutting knives 413 are rotatably installed on the circular cutting knife seat 4 through a rotating shaft 41. The discharging part includes a chopping knife cylinder 13 and a blanking plate 14. The chopping knife cylinder 13 is rotatably installed on the machine body 1 and is located on the side of the circular cutting knife 413 facing away from the slicing knife 6. The blanking plate 14 is located below the chopping knife cylinder 13. The chopping knife cylinder 13, the rotating shaft 41 and the pusher 24 are all connected to the driving device inside the machine body 1. The rotating directions of the pusher 24 and the chopping knife cylinder 13 and the rotating shaft 41 are opposite. The material rotates inside the material guiding cylinder 2 through the pusher 24. The centrifugal force makes the material extend out of the material guiding cylinder 2 at the position of the cutting opening 23. The slicing knife 6 and the circular cutting knives 413 cut the material into dices. The chopping knife cylinder 13 drives the blades on its outer peripheral surface to rotate, and scrapes the material from the circular cutting knives 413 to the position of the blanking plate 14, avoiding blockage of the material at the position of the circular cutting knives 413.

[0041] On one side of the material guide cylinder 2 facing away from the machine body 1, a feed port 25 is provided. The propeller 24 rotates around the central axis of the material guide cylinder 2. A plurality of material guide plates 241 are installed on the circumferential wall of the propeller 24, and the material guide plates 241 are in contact with the inner circumferential wall of the material guide cylinder 2. The material guide cylinder 2 includes a cylinder base 22 and an upper cover 21. The top end of the cylinder base 22 is located on opposite sides of the upper cover 21, the bottom end of the cylinder base 22 is located below the upper cover 21, one side of the cylinder base 22 and the upper cover 21 are hinged to each other, and the other sides of the cylinder base 22 and the upper cover 21 are respectively located on both sides of the cutting opening 23. The slicing knife 6 and the circular cutting knife 413 seat 4 are both installed on the outside of the material guide cylinder 2.

[0042] Referring to Figure 1 and Figure 4 , an adjusting mechanism for adjusting the distance between the upper cover 21 and the slicing knife 6 is installed on the cylinder base 22. The adjusting mechanism includes a screw rod 213 and a support rod 224. The support rod 224 is rotatably installed at the top end of the cylinder base 22, and a lifting rod 3 is rotatably installed at one end of the upper cover 21 close to the cutting opening 23. The support rod 224 is located above the lifting rod 3. The screw rod 213 is rotatably connected to the middle of the support rod 224. The lifting rod 3 is provided with a threaded hole 31 for the screw rod 213 to pass through. The bottom end of the screw rod 213 passes through the threaded hole 31. By rotating the screw rod 213, the lifting rod 3 can be driven to move up and down on the screw rod 213, so that the upper cover 21 can be turned around the hinge point, thereby adjusting the distance between the end of the upper cover 21 close to the cutting opening 23 (referring to Figure 2 ) and the slicing knife 6, changing the size of the cutting opening 23 (referring to Figure 2 ), and thus adjusting the cutting thickness of the fruits and vegetables.

[0043] The lifting rod 3 and the cylinder base 22 are fixed to each other through a fixing mechanism. The fixing mechanism is set as a fastening nut 34. An arc-shaped hole 221 is provided on one side of the cylinder base 22 facing away from the machine body 1. The center position of the arc-shaped hole 221 coincides with the hinge point of the upper cover 21 and the cylinder base 22. One end of the lifting rod 3 passes through the arc-shaped hole 221 and is threadedly connected to the fastening nut 34. The fastening nut 34 is tightened on the side wall of the cylinder base 22 to fix the upper cover 21 and the cylinder base 22 to each other.

[0044] Referring to Figure 2 and Figure 3, a mounting plate 5 is fixed on one side of the cutting port 23 of the cylinder base 22. A slot 52 is formed on the side of the mounting plate 5 close to the cutting port 23. A slicing knife 6 is inserted into the slot 52. The slicing knife 6 is located on the side of the cutting port 23 away from the upper cover 21. The cutting edge of the slicing knife 6 is tangent to the outer peripheral surface of the material guiding cylinder 2. The cutting edge of the slicing knife 6 faces the side opposite to the rotation direction of the pusher 24. One end of the slicing knife 6 away from the machine body 1 extends out of the cylinder base 22 and is provided with a disassembly hole 61, which facilitates the staff to disassemble and assemble the slicing knife 6 with tools and is convenient for cleaning. A positioning post (not marked in the figure) is fixed in the slot 52. A semi-circular groove 62 is formed on the side of the slicing knife 6 close to the machine body 1. The semi-circular groove 62 is engaged with the positioning post to pre-position the installation position of the slicing knife 6.

[0045] Referring to Figure 2 and Figure 5 , two insertion posts 51 are vertically fixed on the mounting plate 5. Installation holes 42 penetrating the top surface are formed on both sides of the bottom surface of the circular cutting knife seat 4. One end of the insertion post 51 away from the mounting plate 5 passes through the installation hole 42 and is threadedly connected with a fastener. The fastener is set as a locking nut 511. Tightening the locking nut 511 can fix the circular cutting knife seat 4 on the mounting plate 5. The circular cutting knife 413 is located on the side of the slicing knife 6 opposite to the cutting port 23. A knife comb 212 is fixed on the side of the upper cover 21 close to the cutting port 23. The knife comb 212 is located between the circular cutting knife seat 4 and the mounting plate 5. The bottom end of the circular cutting knife 413 passes through the knife comb 212. The circular cutting knife 413 cuts the material between the knife comb 212 and the mounting plate 5, which can reduce the cutting resistance of the circular cutting knife 413 to the material and improve the cutting effect.

[0046] A core shaft 11 connected to the driving device is installed on the side wall of the machine body 1 close to the circular cutting knife seat 4. The two ends of the rotating shaft 41 are flush with the side wall of the circular cutting knife seat 4. One end of the rotating shaft 41 is fixed with a square block 411. A square groove 111 is formed on the side wall of one end of the core shaft 11 close to the circular cutting knife seat 4. The square groove 111 is engaged with the square block 411, so that the core shaft 11 can drive the rotating shaft 41 to rotate synchronously.

[0047] An indicating line 412 is formed at one end of the rotating shaft 41 away from the square block 411. The indicating line 412 extends radially from the middle of the rotating shaft 41 to the circumference of the rotating shaft 41. An alignment line 223 is formed on the side wall of the circular cutting knife seat 4 close to the indicating line 412. The chopping knife cylinder 13 and the core shaft 11 rotate synchronously by the driving device. When the circular cutting knife seat 4 needs to be disassembled, rotating the chopping knife cylinder 13 can drive the core shaft 11 and the rotating shaft 41 to rotate. When the extension line of the alignment line 223 coincides with the indicating line 412, the square block 411 can move upward along the length direction of the insertion post 51 to disengage from the square groove 111, which is convenient for disassembling and cleaning the circular cutting knife seat 4.

[0048] A pin shaft 12 connected to a driving device is installed on the side wall of the machine body 1 near the position of the chopping knife cylinder 13. The pin shaft 12 is fixedly connected with an auxiliary support shaft 122 through a flange 121. One end of the auxiliary support shaft 122 far from the pin shaft 12 passes through the chopping knife cylinder 13 and is threadedly connected with a locking member. The locking member is set as a fixing nut 123, and the fixing nut 123 fixes the chopping knife cylinder 13 on the auxiliary support shaft 122. A positioning block 1221 with a hexagonal cross-sectional outer edge is fixed on the side wall of the auxiliary support shaft 122. The positioning block 1221 is fitted and clamped with the inner wall of the chopping knife cylinder 13, so that the pin shaft 12 can drive the auxiliary support shaft 122 to rotate. When the auxiliary support shaft 122 is bent or broken, only the auxiliary support shaft 122 needs to be replaced, which is convenient for maintenance and saves maintenance costs.

[0049] Refer to Figure 1 and Figure 6 On the side of the cylinder base 22 far from the machine body 1, a machine cover 7 is hinged. The machine cover 7 covers the outside of the feeding part, cutting part and discharging part. An inlet hopper 71 is installed on the machine cover 7. The material dropping end of the inlet hopper 71 is communicated with the inlet port 25. An outlet hopper 72 is installed on the machine cover 7. The outlet hopper 72 is sleeved at the position of the material dropping plate 14, providing a guiding effect on the material and at the same time preventing the material from being polluted by dust and impurities.

[0050] Two limiting plates 8 are installed in the inlet hopper 71. The two limiting plates 8 are respectively hinged to the opposite inner walls of the inlet hopper 71. When the two limiting plates 8 approach and close to each other, the two limiting plates 8 can close the material dropping channel of the inlet hopper 71. Push rods 81 are hinged to the bottom surfaces of the sides of the two limiting plates 8 close to each other. One end of the push rod 81 far from the limiting plate 8 is hinged to a sliding rod 82. Sliding holes 711 are opened on the opposite side walls of the inlet hopper 71. The sliding holes 711 are located below the limiting plates 8 and extend away from the limiting plates 8. One end of the sliding rod 82 far from the push rod 81 passes through the sliding hole 711 and is connected with a driving member. The driving member is set as a cylinder 712, and the cylinder 712 is fixed on the outer side wall of the inlet hopper 71.

[0051] On both opposite inner walls of the feed hopper 71, limiting posts 713 are fixed. The limiting posts 713 are located above the material limiting plate 8. The sliding rod 82 is pushed by the air cylinder 712 to slide in the sliding hole 711. When the sliding rod 82 moves to one end of the sliding hole 711 close to the material limiting plate 8, the push rod 81 supports the material limiting plate 8 to flip around the hinge point to a position where it abuts against the limiting posts 713. The two material limiting plates 8 are in a closed state, and the materials above the material limiting plate 8 can be intercepted. When the sliding rod 82 moves to the end of the sliding hole 711 far from the material limiting plate 8, the push rod 81 pulls the material limiting plate 8 to flip away from the limiting posts 713. The material limiting plate 8 is parallel to the side wall of the feed hopper 71. The two material limiting plates 8 are in an unfolded state, and the materials can pass through the feed hopper 71 through the feed port 25 and enter the guide cylinder 2. By the unfolding and closing operations of the two material limiting plates 8, the flow rate of the materials in the feed hopper 71 can be limited, avoiding blockage of the materials at the feed port 25 position, thereby reducing the production efficiency.

[0052] A baffle 821 is fixed on the side wall of the sliding rod 82 and on the outer side of the feed hopper 71. The baffle 821 shields the sliding hole 711 to prevent the materials inside the feed hopper 71 from leaking out of the feed hopper 71 through the sliding hole 711.

[0053] The implementation principle of this embodiment is as follows: The materials pass through the feed port 25 from the feed hopper 71 and enter the inside of the guide cylinder 2. The air cylinder 712 is used to push the sliding rod 82 to slide inside the sliding hole 711. The sliding rod 82 pushes the push rod 81 to support the material limiting plate 8, enabling the two material limiting plates 8 to flip to the mutually closed and unfolded states. When closed, the materials inside the feed hopper 71 can be intercepted. By the extension and closing of the material limiting plate 8, the flow rate of the materials in the feed hopper 71 can be controlled, avoiding blockage of the feed port 25. The propeller 24 rotates to drive the guide plate 241 to rotate. The guide plate 241 drives the materials inside the guide cylinder 2 to rotate at high speed. The materials are subjected to centrifugal force and extend out of the guide cylinder 2 at the cutting opening 23. The slicing knife 6 and the circular cutting knife 413 cut the materials in sequence, causing the materials to be cut into a diced shape. The chopping knife cylinder 13 rotates to sweep the materials on the circular cutting knife 413 onto the blanking plate 14, preventing the materials from being blocked at the position of the circular cutting knife 413 seat 4. Rotating the screw 213 can drive the lifting rod 3 to move on the screw 213. The upper cover 21 can rotate around its rotation connection point with the cylinder base 22. The distance between the upper cover 21 and the slicing knife 6 can be adjusted, changing the height difference between the upper cover 21 and the slicing knife 6, thereby changing the size of the cutting opening 23. Tighten the fastening nut 34 on the outside of the cylinder base 22. The fastening nut 34 abuts tightly against the cylinder base 22 to fix the upper cover 21 and the cylinder base 22 to each other.
