Description

Technical Field

[0001] The invention belongs to the technical field of dried fruit processing equipment, and in particular relates to a dried fruit slicing device. Background Art

[0002] As a convenient and healthy snack food, dried fruits have been favored by consumers in recent years. The processing process usually includes multiple links such as raw material selection, cleaning, core removal, slicing, drying, and packaging. Among them, the slicing link directly affects the taste, appearance and drying efficiency of the final product, so this process is very important.

[0003] Traditional fruit slicing mainly relies on manual operation, which is inefficient and difficult to ensure product consistency. With the development of automation technology, various mechanical slicing devices have emerged, such as rotary blade slicers, drum slicers, reciprocating slicers, belt slicers, etc. These slicing devices have improved production efficiency to a certain extent, but there are also some defects that need to be solved.

[0004] First, the blade structure of the existing slicing device is mostly fixed, and the slice thickness cannot be flexibly adjusted without removing the blade head. This means that if you need to process dried fruit products of different thickness specifications, you need to frequently replace and debug the blade head, which is cumbersome and inefficient.

[0005] Secondly, for the slicing of pitted fruits such as peaches and apples, existing technologies usually require the addition of an independent pitting step. Traditional pitting methods rely on manual operation or complex mechanical structures, which not only increases production costs and safety risks, but also reduces production efficiency. At the same time, after pitting, the pulp needs to be collected manually or automatically before entering the next slicing process. This process breaks the continuity of the production line and adds additional equipment and labor costs. After removal, the pit usually remains on the mechanical structure, requiring additional manual operation or a complex device to be designed to remove it, which increases the complexity of the operation and reduces production efficiency.

[0006] Finally, since it involves the coordination of manual operation and mechanical equipment, the existing dried fruit slicing device has certain safety hazards, such as the operator accidentally touching the blade, being accidentally injured by the core removing machine, etc., which endangers personal safety. Summary of the invention

[0007] In view of the above situation, the present invention provides a dried fruit slicing device, which adopts an adjustable slicing structure to selectively adjust the slice thickness without removing the cutter head, and integrates an automatic core removal function and a pulp and core separation function, thereby realizing the continuity of the production process and improving production efficiency, while effectively avoiding the safety risks and inefficiency problems caused by manual operation.

[0009] Furthermore, the radially contractible fruit slicing mechanism comprises a fixed column and a blade, wherein the fixed column is vertically fixedly arranged on the upper side of the supporting platform, a first disc is coaxially fixedly arranged near the upper end of the fixed column, a first circular hole is provided in a circumferential array near the edge of the first circular disk, a second circular disk is coaxially fixedly arranged at the upper end of the fixed column, a through groove is provided in a circumferential array at the edge of the second circular disk, a fixed shaft is horizontally fixedly arranged at the second circular disk in the through groove, the lower end of the blade is rotatably arranged on the fixed shaft, the tip of the blade faces the axis of the second circular disk, a connecting rod is fixedly arranged at the lower end of the blade, and the blade and the connecting rod are connected. The angle of the rod is less than 90 degrees, and a first slideway is provided on the surface of the connecting rod. A sliding column is provided in the first circular hole for vertical and close sliding operation. A support is fixed at the upper end of the sliding column, and a first sliding shaft is fixed horizontally on the inner side of the support. The first sliding shaft slides closely in the first slideway, and a buffer column is provided in the hollow part at the lower end of the sliding column for close sliding operation. A counterweight contact is fixed at the lower end of the buffer column, and the counterweight contact can drive the sliding column to move downward under the action of gravity until the first sliding shaft contacts the lower end of the first slideway. A buffer spring is provided on the outer side of the buffer column, and both ends of the buffer spring are respectively fixedly connected to the sliding column and the counterweight contact.

[0010] Furthermore, the selective thickness adjustment mechanism includes a sleeve. The sleeve is closely sleeved outside the fixed column under the first disc. A third disc is coaxially fixed on the outer side of the upper end of the sleeve. A second round hole is circumferentially arrayed at a position near the edge of the third disc. A nut is threadedly connected to the outer side of the middle of the sleeve. Three inner rings are sleeved between the nut and the third disc on the outer side of the sleeve. An outer ring is coaxially arranged on the outer side of each inner ring. A retaining rod is fixedly arranged circumferentially between the outer ring and the inner ring of the same layer. The width of the retaining rod is smaller than the width of the solid part between adjacent second round holes on the third disc. When the retaining rod rotates, it can block the second round hole. The number of the second round holes is 16. The number of the retaining rods in one layer is 8, and the number of the retaining rods in each of the remaining layers is 4. Second sliding shafts are horizontally and symmetrically fixed on both sides of the lower end of the sleeve.

[0011] Furthermore, the cam-type intermittent reciprocating driving mechanism includes two support rods. The support rods are vertically and fixedly arranged on the upper side of the support platform. A swing arm is rotatably arranged at the upper end of the support rod far from the fixed column. A runner is rotatably arranged at the upper end of the support rod close to the fixed column. The connection end of the runner and the support rod is concentric with the runner. A concentric circular arc groove and an eccentric circular arc groove are formed on the surface of the runner. The concentric circular arc groove is concentric with the runner. The eccentric circular arc groove is eccentrically arranged away from the axis of the runner. A transition groove is smoothly connected between the two ends of the eccentric circular arc groove and the concentric circular arc groove. A roller is fixedly arranged in the middle of the swing arm. The roller closely slides in the concentric circular arc groove, the transition groove and the eccentric circular arc groove. The radius of the concentric circular arc groove is larger than the radius of the eccentric circular arc groove, so that the duration of the roller in the concentric circular arc groove is long. A U-shaped rod is fixed at one end of the support rod. Second slideways are symmetrically formed on both side sections of the U-shaped rod. The second slideways are in close sliding contact with the second sliding shafts.

[0012] Furthermore, the pneumatic pushing and core-taking mechanism includes a cylinder and a push column. The cylinder and the push column are arranged at intervals and vertically fixed on the lower side of the cross beam of the gantry. An installation rod is horizontally fixed at the output end of the cylinder. A knife barrel is vertically fixed at one end of the installation rod for penetrating through the position of the central core of the fruit. The knife barrel is coaxially sleeved outside the push column. The inner diameter of the knife barrel is larger than the diameter of the push column. The outer diameter of the knife barrel is equal to the diameter of the through hole.

[0013] Furthermore, the fruit core separating and collecting mechanism includes support columns and partition plates. The support columns are arrayed and fixed on the bearing plate. The support columns are located at the rear side edge of the bearing plate in the advancing direction. The connection line between the support columns and the adjacent through holes is parallel to the advancing direction of the bearing plate. A collecting groove is fixed at the upper end of the support columns. The partition plate is vertically arranged at a position slightly below the outer side of the conveying end of the chain plate conveyor. The partition plate is located between the bearing plate in the vertical state and the collecting groove in the horizontal state to realize the separation of the fallen fruit slices and fruit cores.

[0014] Furthermore, a motor is fixedly provided on the support platform, a transmission shaft is coaxially fixedly provided on the output end of the motor, and the transmission shaft is coaxially fixedly connected to each rotating wheel for driving each rotating wheel to rotate synchronously.

[0015] Furthermore, when the chain plate conveyor is paused, the knife cylinder faces the through hole and the fixed column below and the knife edge faces the blade below, and the single conveying distance of the chain plate conveyor is equal to the spacing between two adjacent through holes in the conveying direction.

[0016] Furthermore, the number of second circular holes, first circular holes, through grooves and blade edges in the same group is the same, the diameter of the second circular hole is larger than the diameter of the sliding column and the counterweight contact, the sliding column is coaxially arranged with the second circular hole below, so that the sliding column and the counterweight contact can smoothly pass through the third disc, when the roller is located in the concentric arc groove, the counterweight contact is located above the third disc and the blade is located below the bearing plate, when the roller is located in the middle of the eccentric arc groove, the lowest baffle bar can push the counterweight contact to drive the blade tip to vertically contact the outer wall of the knife barrel, thereby achieving complete cutting of the fruit.

[0017] Furthermore, after the chain plate conveyor is paused, the output end of the cylinder pushes the knife drum down into the through hole to penetrate the center of the fruit core. After the knife drum is pressed down into the through hole, the roller enters the transition groove from the concentric arc groove, so that the blade closes upward and starts to cut the fruit. After the roller enters the concentric arc groove from the transition groove, the output end of the cylinder retracts and the chain plate conveyor conveys synchronously. When the lower end of the knife drum moves up to the horizontal height above the collecting groove, the push column pushes the core in the knife drum out to the collecting groove just below, thereby collecting the core. During a single conveying cycle of the chain plate conveyor, the roller is always located in the concentric arc groove to prevent the blade from obstructing the movement of the carrier plate.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:

[0019] (1) The present invention realizes flexible adjustment of the thickness of fruit slices through a selective thickness adjustment mechanism. The mechanism selectively makes the baffles of different layers contact with the sliding column by loosening and tightening the nut and adjusting the rotation angle of the baffle rod. Since the number and distribution of baffle rods on each layer are different, the number of baffle rods blocking the sliding column leads to different numbers of blades closing upward, thereby realizing the adjustment of the slice thickness and the switching between slicing and dicing.

[0020] (2) The present invention realizes automatic fruit core removal through a pneumatic pushing and core removal mechanism. When the chain plate conveyor transports the fruit to the bottom of the knife cylinder, the cylinder drives the knife cylinder to press down and accurately penetrates the center of the fruit. After the blade completes cutting the fruit, the cylinder retracts, the knife cylinder moves up, and the push column pushes the fruit core in the knife cylinder into the collection tank, completing the core removal process.

[0021] (3) The present invention realizes the automatic separation and collection of fruit cores and fruit slices by arranging a fruit core collecting mechanism at the end of the chain plate conveyor. The collecting mechanism is composed of a support and a partition plate. When the supporting plate is conveyed to the end, the fruit slices slide along the supporting plate and finally fall into one side of the partition plate, while the fruit cores fall directly at the collecting trough and fall into the other side of the partition plate, thereby realizing the effective separation of fruit cores and fruit slices.

[0022] (4) The present invention integrates a radial contraction type fruit slicing mechanism and a pneumatic pushing and core removal mechanism into the same device, and under the drive of a cam type intermittent reciprocating drive mechanism, the fruit slicing and core removal processes are carried out simultaneously. After the chain plate conveyor transports the fruit to the processing position, the pneumatic pushing and core removal mechanism pushes out the fruit core to complete the core removal. After the slicing and core removal are completed, the chain plate conveyor continues to convey and start processing the next fruit. This integrated design avoids the problems of cumbersome process and low efficiency caused by the separate operation of slicing and core removal in the traditional process, and realizes the continuity and automation of the production process.

[0023] (5) The present invention adopts an automated design. Except for the initial placement of the fruit, all other operations are completed automatically by the device without human intervention. This automated operation can not only significantly improve production efficiency and reduce labor costs, but also effectively avoid the safety risks brought by traditional manual operations, such as blade cuts and injuries during core removal operations, thereby improving the safety of the production process.

[0041] The selective thickness adjustment mechanism 5 comprises a sleeve 51, which is tightly sleeved on the outer side of the fixed column 41 below the first disc 42. A third disc 52 is coaxially fixed on the outer side of the upper end of the sleeve 51. The third disc 52 is provided with a second circular hole 521 in a circumferential array near the edge.

[0042] Among them, the cam intermittent reciprocating drive mechanism 6 includes two support rods 61, which are vertically and fixedly arranged on the upper side of the support platform 3. At the upper end of the support rod 61 far from the fixed column 41, a swing arm 62 is rotatably arranged. At the upper end of the support rod 61 close to the fixed column 41, a runner 63 is rotatably arranged. The connection end of the runner 63 and the support rod 61 is concentric with the runner 63. A concentric arc groove 64 and an eccentric arc groove 65 are formed on the surface of the runner 63. The concentric arc groove 64 is concentric with the runner 63, and the eccentric arc groove 65 is eccentrically arranged away from the axis of the runner 63. A transition groove 66 is smoothly connected between the two ends of the eccentric arc groove 65 and the concentric arc groove 64. A roller 67 is fixedly arranged in the middle of the swing arm 62. The roller 67 closely slides in the concentric arc groove 64, the transition groove 66 and the eccentric arc groove 65. The radius of the concentric arc groove 64 is greater than the radius of the eccentric arc groove 65. One end of the support rod 61 is fixedly provided with a U-shaped rod 68. Second slideways 69 are symmetrically formed on both side sections of the U-shaped rod 68. The second slideways 69 are in close sliding contact with the second slide shafts 511.

[0043] Among them, the pneumatic pushing and core-taking mechanism 7 includes a cylinder 71 and a push column 74. The cylinder 71 and the push column 74 are arranged at intervals and vertically and fixedly arranged on the lower side of the cross beam of the gantry 1. A mounting rod 72 is horizontally and fixedly arranged at the output end of the cylinder 71. A cutter barrel 73 is vertically and fixedly arranged at one end of the mounting rod 72. The cutter barrel 73 is coaxially sleeved outside the push column 74. The inner diameter of the cutter barrel 73 is greater than the diameter of the push column 74. The outer diameter of the cutter barrel 73 is equal to the diameter of the through hole 22. The fruit core separating and collecting mechanism 8 includes a support column 81 and a partition plate 83. The support columns 81 are arrayed and fixedly arranged on the bearing plate 21. The support columns 81 are located at the rear side edge of the bearing plate 21 in the advancing direction. The connection line between the support column 81 and the adjacent through hole 22 is parallel to the advancing direction of the bearing plate 21. A collecting groove 82 is fixedly arranged at the upper end of the support column 81. The partition plate 83 is vertically arranged at a position slightly below the outer side of the conveying end of the chain plate conveyor 2. The partition plate 83 is located between the vertically arranged bearing plate 21 and the horizontally arranged collecting groove 82.

[0044] Among them, a motor 9 is fixedly arranged on the support platform 3. The output end of the motor 9 is coaxially and fixedly provided with a transmission shaft 91. The transmission shaft 91 is coaxially and fixedly connected to each runner 63. When the chain plate conveyor 2 pauses, the cutter barrel 73 is directly below the through hole 22 and the fixed column 41, and the cutting edge 23 is directly below the blade 44. The distance of a single conveyance of the chain plate conveyor 2 is equal to the distance between two adjacent through holes 22 in the conveying direction. The number of the second round holes 521, the first round holes 421, the through grooves 431 and the cutting edges 23 in the same group is the same. The diameter of the second round hole 521 is greater than the diameters of the sliding column 46 and the counterweight contact head 471. The sliding column 46 is coaxially arranged with the second round hole 521 below. When the roller 67 is located in the concentric arc groove 64, the counterweight contact head 471 is located above the third disc 52 and the blade 44 is located below the bearing plate 21. When the roller 67 is located in the middle of the eccentric arc groove 65, the lowermost stop rod 56 can push the counterweight contact head 471 to drive the tip of the blade 44 to be vertically and completely in contact with the outer wall of the cutter barrel 73.

[0045] Among them, after the chain plate conveyor 2 is paused, the output end of the cylinder 71 pushes the knife drum 73 down into the through hole 22. After the knife drum 73 is pressed down into the through hole 22, the roller 67 enters the transition groove 66 from the concentric arc groove 64. After the roller 67 enters the concentric arc groove 64 from the transition groove 66, the output end of the cylinder 71 retracts and the chain plate conveyor 2 conveys synchronously. When the lower end of the knife drum 73 moves up to the horizontal height above the collecting groove 82, the push column 74 pushes the fruit core in the knife drum 73 out to the collecting groove 82 just below at this time. During a single conveying cycle of the chain plate conveyor 2, the roller 67 is always located in the concentric arc groove 64.

[0046] During specific use, workers sequentially place fruits in a positive direction at a position just above the through hole 22 on each carrier plate 21. The carrier plate 21 on which fruits are placed is connected by a chain on the chain plate conveyor 2 and is pulled to the bottom of the gantry 1. The chain plate conveyor 2 is widely used in various industries due to its advantages such as stable transportation, high rigidity, strong bearing capacity, and flexible layout. It is common knowledge that the conveying distance and timing of each conveying of the chain plate conveyor 2 are controlled by a motor drive unit and a programmable logic control unit. Therefore, the specific structural design and use principle of the chain plate conveyor 2 used in the present device are not shown in detail. When the fruit comes to the bottom of the knife drum 73, the carrier plate 21 stops moving forward. Under the control of the pneumatic control unit and the programmable logic control unit, the output end of the cylinder 71 extends to drive the knife drum 73 to pass through the center of the fruit core and enter the through hole 22. Then, the continuously rotating runner 63 causes the roller 67 to enter the transition groove 66 from the concentric arc groove 64. Since the concentric arc groove 64 is concentrically arranged with the runner 63 The rotating wheel 63 rotates along its own axis. Therefore, before this, when the roller 67 moves in the concentric arc groove 64, the positions of the roller 67 and the swing arm 62 will not change. When the roller 67 enters the transition groove 66, the swing arm 62 will rotate upward along the connecting end of the support rod 61, and the shaped rod 68 drives the second sliding shaft 511 to move upward along the fixed column 41 through the second slideway 69, thereby driving the blocking rod 56 and the third disc 52 to move upward. The counterweight contact 471 is previously driven by gravity to drive the sliding column 46 and the connecting rod 45 to move upward. Then it falls to the lowest position while the blade 44 is located below the carrying plate 21. At this time, the counterweight contact 471 passes through the second circular hole 521 and is blocked by the blocking rod 56 to move upward passively. The force transmitted by the buffer spring 48 drives the sliding column 46 to move upward, and then drives the connecting rod 45 and the blade 44 to rotate upward around the fixed axis 432. After the blade 44 passes through the upper cutting edge 23, it closes in a petal shape. When the roller 67 is located in the middle of the eccentric arc groove 65, the tip of the blade 44 is completely in close contact with the outer wall of the knife cylinder 73 to achieve the cutting of the fruit.

[0047] Then the roller 67 enters the transition groove 66, so that the blade 44 gradually expands. When the roller 67 enters the concentric arc groove 64, the blade 44 is fully expanded and located below the carrier plate 21. Then the output end of the cylinder 71 retracts and the chain plate conveyor 2 conveys synchronously. When the lower end of the knife barrel 73 moves up to the horizontal height above the collection groove 82, the fruit core stuck in the knife barrel 73 has been pushed out of the knife barrel 73 by the upper push column 74 for a distance, and then falls into the collection groove 82 just passing below, realizing the separation and collection of the fruit core. The conveyor 2 continues to convey until the next row of fruits comes to the bottom of the knife drum 73, then stops and starts to cut and remove the cores of the next row of fruits. The cut fruit slices are spread on the supporting plate 21 and finally come to the conveying end under the conveyance of the chain plate conveyor 2. Due to the provision of the partition plate 83, when the supporting plate 21 is close to the vertical state at the end, the fruit slices adhere to the surface of the supporting plate 21 and pass through the support 81 to fall to one side of the partition plate 83, while the cores fall to the other side of the partition plate 83 when the collecting trough 82 is horizontally downward, thereby realizing the separation and collection of fruit slices and cores.

[0048] When it is necessary to adjust the slice thickness, the selective thickness adjustment mechanism 5 will play a role. The blade 44 can only be closed when the baffle rod 56 blocks the counterweight contact 471. If the baffle rod 56 does not block the counterweight contact 471, the slide column 46 and the counterweight contact 471 will remain unchanged and pass through the second circular hole 521, so the corresponding blade 44 will not close, thereby realizing selective cutting. The number of baffle rods 56 on each layer is set to 4, 4 and 8 respectively. When it is necessary to cut a fruit into 16 slices, first loosen the nut 53, rotate the baffle rod 56 on each layer so that all the baffle rods do not overlap and block all the second circular holes 521, and then tighten the nut 53. When it is necessary to cut 8 slices, the two layers of baffle rods containing 4 overlap and overlap with 4 of the baffle rods in the first layer of baffle rods 56 containing 8, and the 8 baffle rods of this layer block the 8 second circular holes 521. When there are four pieces, or to be more precise, four gear rods on one layer block the four second circular holes 521, and the gear rods 56 on the other layers rotate to the positions between the adjacent second circular holes 521. The above operations realize the adjustment of equal cutting thickness and the switching between sheet and block. Since the gear rods 56 have a certain thickness, the gear rods 56 on different layers push the sliding column 46 to different heights, which makes the final positions of the blades 44 after closing different and cannot smoothly achieve the perfect fit with the knife barrel 73. At this time, the buffer column 47 and the buffer spring 48 will play a role. If the setting is reasonable so that the gear rods 56 on the bottom layer can push the blade 44 to fit with the knife barrel 73, the gear rods 56 on the upper layer will push the blade 44 to fit with the knife barrel 73, and the gear rods 56 will continue to move up a short distance. At this time, the buffer spring 48 is compressed to prevent the blade 44 from pressing the knife barrel 73 forcibly and causing damage.
