Description

Technical Field

[0001] The present invention belongs to the technical field of cutter heads, and particularly relates to a scale-adjustable cutter head. Background Art

[0002] A variety of tool sizes and specifications are installed on the surface of the cutter head. When the cutter head rotates at a high speed, it drives all the tools to revolve around the main shaft, and then uniformly pushes the fruits and vegetables to move horizontally. The fruits and vegetables gradually approach the cutter head, come into contact with the blades, and the blades slice the surface of the uniformly horizontally moving fruits and vegetables.

[0003] There are various thickness requirements for fruit and vegetable slices. Usually, different thickness slices need to be cut in different situations to meet the corresponding needs. The existing cutter head mainly has the following technical problems in the actual operation process: Since the fruits and vegetables themselves have a certain hardness, and there is a centrifugal force when the cutter head rotates, if the fruit and vegetable slices need to be cut very thick, at a constant cutter head rotation speed, it is necessary to push the fruits and vegetables at a faster speed. The faster the fruits and vegetables are pushed, the thicker the slices will be. There is a gap between the cutter head and the blades, and the fruits and vegetables will move quickly along the gap between the cutter head and the blades. The distance that the fruits and vegetables extend towards the blades is very far. When the cutter head rotates, it is easy for any adjacent blade to cut into the middle part of the fruits and vegetables. Affected by the centrifugal force, the fruits and vegetables are easily stuck between the cutter head and the blades. Then, the tools are prone to uneven force, resulting in blade deformation or fracture, easy tool jamming, making the slicing process not smooth, unable to cut the fruit and vegetable slices too thick, having limitations on the thickness of the fruit and vegetable slices, and only being able to move the fruits and vegetables at a small moving speed uniformly to avoid blade damage, which will reduce the slicing processing efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and solve the problem that the existing cutter head cannot slice fruits and vegetables at a too fast speed and is easy to damage the blades.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a scale-adjustable cutter head, including a cutter head and blades. There is a pair of the cutter heads. The blades are located inside the same horizontal plane between the two cutter heads. A secondary tool holder is installed at the lower end of the blades. A main tool holder is installed at the lower end between the two cutter heads below the secondary tool holder. A main shaft is interspersed between the main tool holder and the secondary tool holder. A chuck is installed at the lower end of the main shaft;

[0006] A partition tube is sleeved on the upper side of the main shaft. A pair of concave cavities symmetrically distributed at the head and tail are opened on the lower side around the partition tube. The head and tail ends of the chuck respectively extend into the adjacent concave cavities, and the head and tail ends of the chuck are respectively slidably connected to the inside of the adjacent concave cavities;

[0007] A distance-adjusting tube is sleeved on the upper side of the periphery of the partition tube. A pair of semi-circular spiral through grooves are formed on the periphery of the distance-adjusting tube. The head and tail ends of the clamping block respectively extend out of the outer ends of the adjacent semi-circular spiral through grooves from the inside of the adjacent concave cavities, and the head and tail ends of the clamping block are respectively movably connected with the inside of the adjacent semi-circular spiral through grooves.

[0008] In a preferred technical solution of the present invention, a cushion block is installed at the lower end of the clamping block, a secondary shaft is installed at the lower end of the cushion block, and a rotating disk, a partition disk and a scale disk are sequentially sleeved on the lower side of the periphery of the secondary shaft from top to bottom. The partition tube and the distance-adjusting tube are located at the upper end of the rotating disk.

[0009] In a preferred technical solution of the present invention, a semi-circular cavity is formed on the surface of the scale disk, and a threaded port convex seat rotatably connected between the rotating disk and the partition disk is movably connected with the inside of the semi-circular cavity. The lower end of the threaded port convex seat is threadedly connected with a screw button closely attached to the lower end of the scale disk.

[0010] In a preferred technical solution of the present invention, the lower end of the distance-adjusting tube is detachably connected with the upper end of the rotating disk through a lock catch, the lower end of the rotating disk is detachably connected with the upper end of the partition disk through a screw, the lower end of the partition disk is rotatably connected with the upper end of the scale disk, and the lower end of the scale disk is integrally formed with scale lines adjacent to one side of the semi-circular cavity. The secondary shaft is located between the scale lines and the semi-circular cavity.

[0011] In a preferred technical solution of the present invention, a hand crank is detachably connected to the lower end of the secondary shaft through a screw, and a driving shaft is detachably connected to the upper end of the main shaft through a screw.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0013] Blades are arranged on the inner side of the same horizontal plane between a pair of cutter disks. The secondary tool rest and the main tool rest are connected by inserting the main shaft. The clamping block on the main shaft cooperates with the concave cavity of the partition tube and the semi-circular spiral through groove of the distance-adjusting tube. When the distance-adjusting tube is rotated, the clamping block moves in the semi-circular spiral through groove. Since the clamping block is slidably connected with the concave cavity of the partition tube, the secondary tool rest is driven to move relative to the main tool rest along the main shaft. The clamping block moves in the concave cavity of the partition tube and the semi-circular spiral through groove of the distance-adjusting tube, so that the distance between the secondary tool rest and the main tool rest can be adjusted by rotating the distance-adjusting tube, the distance between the cutter disk and the blade can be adjusted, and thus the distance between the cutter disk and the blade can be flexibly adjusted. By adjusting the distance between the cutter disk and the blade, the thickness of the fruit and vegetable slices can be adjusted, and the thickness of various fruit and vegetable slices can be arbitrarily adjusted.

[0014] Since the main tool rest connects the two cutter disks into one body and holds them in a stable supporting state, and the auxiliary tool rest stably supports the blade at the position between the two main tool rests, a stable cross-supporting structure is formed between the main tool rest and the auxiliary tool rest, enabling the cutter disk and the blade to be stably installed. The shearing force of the fruit and vegetable slices will be evenly distributed on the surfaces of the main tool rest and the auxiliary tool rest, avoiding damage caused by blade deformation and fracture. It is possible to select a thicker slice thickness with a faster moving speed of the fruit and vegetables. Thickening the slice thickness can also improve the slicing processing efficiency.

[0015] Loosening the screw knob allows the dial and the dividing disk to rotate relative to each other. Observe the scale lines on the lower end of the dial to rotate the dial. The semi-circular cavity, the threaded port boss, and the screw knob are used in cooperation. Refer to the scale lines to accurately and intuitively control the adjustment amount of the distance between the cutter disk and the blade, meeting the requirements of different cutting scenarios for the tool distance. Tightening the screw knob can fix the distance between the cutter disk and the blade after adjustment.

[0016] The lower end of the auxiliary shaft is connected to a hand crank, which facilitates the operator to manually drive the rotation of the scale-adjustable cutter disk, with simple and convenient operation. At the same time, the upper end of the main shaft is connected to a drive shaft, which is convenient for connecting an external power source to realize the driving operation of the cutter disk. It can be used electrically in places with power supply or manually in places without power supply, breaking the limitations of the usage occasion and killing two birds with one stone.

A rotating disk 13, a separating disk 14 and a graduated disk 15 are sequentially inserted into the lower side of the periphery of the secondary shaft 8 from top to bottom, and the separating tube 9 and the pitch-adjusting tube 11 are located at the upper end of the rotating disk 13; a semi-circular cavity 17 is provided on the surface of the graduated disk 15; the lower end of the pitch-adjusting tube 11 is detachably connected to the upper end of the rotating disk 13 by a lock buckle, and the lower end of the rotating disk 13 and the upper end of the separating disk 14 are connected by a screw The nails are detachably connected, the lower end of the separating plate 14 is rotatably connected to the upper end of the scale plate 15, the lower end of the scale plate 15 is integrally formed with a scale line 18 adjacent to one side of the semi-annular cavity 17, and the secondary shaft 8 is located between the scale line 18 and the semi-annular cavity 17; the main shaft 5 connects the main tool holder 4, the secondary tool holder 3, the knife disc 1 and the blade 2 into one body, and the upper end of the main shaft 5 is detachably connected to the driving shaft 20 by screws, one end of the driving shaft 20 is installed on the main shaft 5, and the other end of the driving shaft 20 is installed on the slicer driving device (for example, the shaft of the motor). When used in a place with a power supply, the upper end of the main shaft 5 is connected to the driving shaft 20, which is convenient for connecting an external power source. The driving shaft 20 rotates by means of electric drive, and the driving shaft 20 will be rotated in sequence The main shaft 5, the block 6, the cushion block 7 and the secondary shaft 8 are driven to rotate synchronously, and the two concave cavities 10 are respectively in contact with the head and tail ends of the block 6. The block 6 drives the partition tube 9 to rotate inside the concave cavity 10, and the partition tube 9 and the distance adjustment tube 11 will also rotate synchronously with the rotation of the main shaft 5, the block 6, the cushion block 7, and the secondary shaft 8 to realize the driving operation of the cutter disc; when used in a place without power supply, the lower end of the secondary shaft 8 is detachably connected to a hand crank 19 by a screw, and the hand crank 19 is connected to the lower end of the secondary shaft 8, so that the operator can manually drive the scaled adjustable cutter disc to rotate. The operation is simple and convenient, and it can be used electrically in a place with power supply or manually in a place without power supply, breaking the limitations of the usage occasions and killing two birds with one stone.

[0041] A pair of cutter discs 1 are provided with blades 2 on the inner side of the same horizontal plane in the middle. The secondary tool rest 3 and the main tool rest 4 are connected by inserting the main shaft 5. The main tool rest 4 and the secondary tool rest 3 will revolve with the rotation of the main shaft 5. The cutter disc 1 will rotate with the rotation of the main tool rest 4, and the blade 2 will rotate with the rotation of the secondary tool rest 3. The cutter disc 1 and the blade 2 are driven by the main shaft 5 to revolve around the distance adjustment pipe 11 and the separation pipe 9. When fruits and vegetables pass through the gap between the cutter disc 1 and the blade 2, the cutter disc 1 and the blade 2 cut the fruits and vegetables into slices.

[0042] Inside the semi-circular cavity 17, there is a threaded port boss 21 rotatably connected between the rotating disk 13 and the partition disk 14. The lower end of the threaded port boss 21 is threadedly connected to a screw knob 16 closely attached to the lower end of the scale disk 15. When it is necessary to adjust the distance between the cutter head 1 and the blade 2, stop the rotation of the cutter head, loosen the screw knob 16, and the screw knob 16 moves away from the scale disk 15. Then, the scale disk 15 and the partition disk 14 can rotate relative to each other. Observe the scale lines 18 opened at the lower end of the scale disk 15 to rotate the scale disk 15. The threaded port boss 21 can move inside the semi-circular cavity 17. The cooperation between the threaded port boss 21 and the semi-circular cavity 17 can keep the rotating partition disk 14 and the scale disk 15 rotating concentrically. The partition disk 14 drives the rotating disk 13 to rotate synchronously. The rotating disk 13 drives the distance adjustment tube 11 to rotate. The semi-circular spiral through groove 12 revolves around the partition tube 9 synchronously as the distance adjustment tube 11 rotates. The changing form of the rotation of the semi-circular spiral through groove 12 presents an up-and-down transmission movement like a spiral. The head and tail ends of the block 6 are frictionally moved by the rotation of the corresponding semi-circular spiral through groove 12. The block 6 will slide up and down inside the concave cavity 10 as the semi-circular spiral through groove 12 rotates. The block 6 makes the distance adjustment tube 11 slide up and down along the periphery of the partition tube 9 by relying on the semi-circular spiral through groove 12. Since the block 6, the spacer 7, the main shaft 5, and the auxiliary shaft 8 are on the same vertical line as the drive shaft 20 and are simultaneously connected to the slicing machine, the distance adjustment tube 11 and the partition tube 9 are in a relative motion state, while the partition tube 9 is in a relative static state with the block 6, the spacer 7, the main shaft 5, and the auxiliary shaft 8 at the same time. The distance adjustment tube 11 drives the main tool holder 4 to move up and down. The blade 2 is in a static state, and the cutter head 1 is in a moving state. The distance between the cutter head 1 and the blade 2 changes. The auxiliary tool holder 3 and the main tool holder 4 gradually stagger or approach each other, and the distance between the auxiliary tool holder 3 and the main tool holder 4 changes. The semi-circular cavity 17, the threaded port boss 21, and the screw knob 16 cooperate with each other, so that the cutter head 1 and the blade 2 are staggered from each other and not on the same horizontal plane, or the cutter head 1 and the blade 2 gradually approach each other and are close to the same horizontal plane, changing the distance between the cutter head 1 and the blade 2. By changing the axial distance between the blade 2 and the cutter head 1, the cutting thickness is adjusted, reflecting the large pitch axial movement adjustment technology of the cutter head 1. When the distance adjustment tube 11 rotates, the threaded port boss 21 and the screw knob 16 will move along the scale disk 15 inside the semi-circular cavity 17. The screw knob 16 points to different positions of the scale lines 18, and the positions of the rotation adjustment of the distance adjustment tube 11, the rotating disk 13, and the partition disk 14 are shown by the scale disk 15. Users can clearly perceive the result after adjustment. While observing the scale lines 18, rotate the distance adjustment tube 11, and the thickness range of the required finished product can be adjusted at one time. Refer to the scale lines 18 to accurately and intuitively control the adjustment amount of the distance between the cutter head 1 and the blade 2, meeting the requirements of the knife distance for different cutting scenarios. Changing the distance between the cutter head 1 and the blade 2 will change the position where the cutter head 1 and the blade 2 contact the surface of the fruit and vegetable, and will change the thickness of the sliced fruit and vegetable.

[0043] The chuck 6 on the main shaft 5 cooperates with the concave cavity 10 of the partition pipe 9 and the semi-circular spiral through groove 12 of the distance-adjusting pipe 11. When the distance-adjusting pipe 11 is rotated, the chuck 6 moves within the semi-circular spiral through groove 12. Since the chuck 6 is slidably connected to the concave cavity 10 of the partition pipe 9, the sub-tool rest 3 is driven to move along the main shaft 5 relative to the main tool rest 4. The chuck 6 moves within the concave cavity 10 of the partition pipe 9 and the semi-circular spiral through groove 12 of the distance-adjusting pipe 11, enabling the distance between the sub-tool rest 3 and the main tool rest 4 to be adjusted by rotating the distance-adjusting pipe 11, thereby adjusting the distance between the cutter disc 1 and the cutter blade 2. The spacer 7 effectively reduces the wear of the chuck 6 during movement, making the chuck 6 slide more smoothly, so that the distance between the cutter disc 1 and the cutter blade 2 can be flexibly adjusted. By adjusting the distance between the cutter disc 1 and the cutter blade 2, the thickness of the fruit and vegetable slices can be adjusted, and various slice thicknesses of fruits and vegetables can be arbitrarily adjusted.

[0044] After adjusting the distance between the cutter disc 1 and the cutter blade 2, tighten the screw knob 16. The screw knob 16 presses tightly against the surface of the scale disc 15 again. The screw knob 16 restricts the convex seat 21 of the threaded port from moving along the inside of the semi-circular cavity 17, so that the partition disc 14 and the rotating disc 13 cannot rotate, and thus the distance-adjusting pipe 11 cannot rotate. Therefore, the chuck 6 will remain stationary in the semi-circular spiral through groove 12 at its original position, and the main shaft 5, the sub-shaft 8, the chuck 6, and the spacer 7 will no longer move along the inner wall of the partition pipe 9, and the distance between the cutter disc 1 and the cutter blade 2 after adjustment can be fixed.

[0045] Since the main tool rest 4 connects the two cutter discs 1 together and holds them in a stable supporting state, the sub-tool rest 3 stably supports the cutter blade 2 at the position between the two main tool rests 4. A stable cross-supporting structure is formed between the main tool rest 4 and the sub-tool rest 3. A "U" - shaped structure is formed between the cutter disc 1 and the main tool rest 4, an "S" - shaped structure is formed between the cutter blade 2 and the sub-tool rest 3, and a "cross" - shaped cross - arrangement state is presented between the sub-tool rest 3 and the main tool rest 4. The main tool rest 4 and the sub-tool rest 3 commonly use the main shaft 5 as the cross - center point, making the cutter disc 1 and the cutter blade 2 installed stably. The acting force generated when the cutter disc 1 and the cutter blade 2 cut fruits and vegetables will be transmitted to the main tool rest 4 and the sub-tool rest 3. The acting force gathers towards the main shaft 5 along the main tool rest 4 and the sub-tool rest 3. The acting force gathers to the main shaft 5 along the main tool rest 4 and the sub-tool rest 3 respectively. The main tool rest 4 and the sub-tool rest 3 will respectively bear the force of cutting fruits and vegetables by the cutter disc 1 and the cutter blade 2, reducing the acting force of cutting fruits and vegetables borne by the cutter disc 1 and the cutter blade 2. The shearing force of the fruit and vegetable slices will be evenly distributed on the surfaces of the main tool rest 4 and the sub-tool rest 3, avoiding the phenomenon of damage caused by the deformation and fracture of the cutter blade. A faster moving speed of the fruits and vegetables can be adopted to select a thicker slice thickness, and while the slice thickness is increased, the slicing processing efficiency can also be accelerated.

[0046] When the rotational speed of the cutter head remains constant, the faster the moving speed of the fruits and vegetables, the larger the position interval of each section where each blade 2 contacts the surface of the fruits and vegetables. The more quickly the graduated adjustable cutter head slices the fruits and vegetables, the thicker the slice thickness. The reverse process results in the opposite outcome. When the moving speed of the fruits and vegetables remains constant and the rotational speed of the cutter head is changed, the faster the rotational speed of the cutter head changes, the higher the frequency of contact between blade 2 and the surface of the fruits and vegetables. The more quickly the cutter head slices the fruits and vegetables, and at the same time the slice thickness is thinner. The reverse process results in the opposite outcome. If the above factors are kept unchanged, simply changing the distance between blade 2 and cutter head 1 will also change the slice thickness of the fruits and vegetables, expanding the function of adjusting the slicing effect of the fruits and vegetables.

[0047] Combining the above steps, the slice thickness can be changed by changing the moving speed of the fruits and vegetables, and can also be changed by adjusting the distance between cutter head 1 and blade 2. When different slice thicknesses are required, only the distance between cutter head 1 and blade 2 needs to be changed, without considering the factor that whether the moving speed of the fruits and vegetables is too fast will cause damage to the cutter head. During the slicing process, a relatively fast moving speed of the fruits and vegetables can generally be used for slicing. The slicing speed is very fast, and the slice thickness can also be made very thick. Without reducing the speed, the slice thickness can be changed on the premise that the moving speed of the fruits and vegetables is very fast. The selection range of the slice thickness is wide, which can not only make the slicing process smoother, but also improve the slicing efficiency.

[0048] The structure of cutter head 1 flexibly realizes multiple driving methods, and the connection between cutter head 1 and the machine also provides two methods of convex shaft connection and shaft hole connection, enabling the cutter head to adapt to different machine connection ports.
