[0047] The application will be further described below in conjunction with specific examples.

[0048] Example 1: as Figures 1-24 shown, a pitaya slicing device, comprising a feeding device 1, a limiting device 2, a slicing mechanism 3, a tray pushing device 4 and a discharging conveyor belt 5, the discharge port of the feeding device 1 is opposite to the feeding port of the slicing mechanism 3, the limiting device 2 is installed on the slicing mechanism 3 to limit the incoming pitaya, the slicing mechanism 3 is installed above the discharging conveyor belt 5, the tray pushing device 4 is installed at one end of the discharging conveyor belt 5 and can push the tray 6 onto the discharging conveyor belt 5.

[0049] The application can greatly reduce the personal safety hazards to workers, ensure the health and environmental protection of pitaya, and improve the production and processing efficiency without damaging the pitaya, realizing the separation of the four links of feeding, slicing, tray placing and discharging from manual operation. In normal operation, the technical personnel only need to ensure that the pitaya placed on the feeding conveyor belt meets the basic requirements of the equipment. After the equipment is running, the pitaya slices will be placed on the baking tray in the specified size (5X5 slices) and transported to the discharging conveyor belt. The workers can place the pitaya in the baking oven for baking.

[0050] The above-mentioned feeding device 1 comprises a feeding belt conveyor 101 and a pushing mechanism 102, the feeding belt conveyor 101 is installed in parallel beside the discharging conveyor belt 5, and the discharging end is connected to the feeding port of the slicing mechanism 3 through the installed pushing mechanism 102. The feeding belt conveyor 101 is vertically provided with a partition plate 103 in the length direction of the belt. The upper end surface of the rack on both sides of the feeding belt conveyor 101 is provided with a baffle higher than the partition plate, so as to prevent the pitaya from falling off from both sides during transportation. The feeding belt conveyor 101 is responsible for transporting the pitaya to be processed. Before starting processing, pitaya is placed on the conveyor belt (5 pieces are placed in a grid). There are a total of 20 grids on the conveyor belt, and it is expected to complete the processing in 10 minutes. A total of 120 trays of pitaya can be processed. The feeding belt conveyor sends the pitaya into the pushing mechanism 102, and the pushing mechanism pushes the pitaya into the feeding port of the slicing device.

[0051] The pushing mechanism 102 comprises a pushing belt conveyor 104, a pushing plate 105 and a slope transition plate 106. The pushing belt conveyor 104 is vertically installed at the end of the feeding belt conveyor 101 and is lower than the feeding belt conveyor 101. The pushing plate 105 is vertically fixedly connected to the belt of the pushing belt conveyor 104. The high end of the slope transition plate 106 is connected to the discharging end of the pushing belt conveyor 104, and the bottom end is connected to the feeding port of the slicing mechanism 3. The frame of the pushing belt conveyor 104 is fixedly connected to the end of the frame of the two feeding belt conveyors 101. The frame of the pushing belt conveyor 104 is provided with inclined plates on both sides, which facilitates the feeding of pitaya and avoids the pitaya from falling off the belt conveyor. When the pitaya is fed by the feeding belt conveyor, the pushing mechanism pushes the pitaya into the slope transition plate (the speed needs to meet the requirement of pushing the pitaya into the feeding port of the slicing device). The slope transition plate rolls the pitaya with momentum into the feeding port, which facilitates the smooth feeding of the pitaya into the slicing device.

[0052] The limiting device 2 comprises a linkage horizontal limiting mechanism and a vertical limiting mechanism. The horizontal limiting mechanism is used for limiting a row of pitaya in the horizontal direction, and the vertical limiting mechanism is used for limiting a row of pitaya in the vertical direction. The linkage structure facilitates the arrangement of a power mechanism, is more compact in structure, is lower in cost, is simpler in control, and ensures that the two movements do not interfere with each other.

[0053] The limiting device 2 comprises horizontal pressing blocks 201, vertical pressing blocks 202, horizontal push rods 203, end face cams 204, vertical pressing rods 205, connecting rods 206 and baffles 207. The baffles 207 and the horizontal pressing blocks 201 are located on both sides of the vertical pressing blocks 202. The bottom surface of the horizontal pressing blocks 201 is in contact with the inner bottom surface of the machine box (which can prevent rotation). The two ends of the horizontal pressing blocks 201 are slidably connected to the horizontal sliding grooves 210 of the two horizontal plates 209 on both sides through sliding pins 208. The horizontal pressing blocks 201 are provided with four horizontal return springs 224 near the two ends. The horizontal return springs 224 are connected to the side surface of the horizontal plate 209 on one side of the slot end face cam 204. The two horizontal plates 209 are installed on both sides of the machine box 306 of the slicing mechanism 3. The machine box 306 is provided with a notch 228 which is connected to the slope transition plate 106. The baffle 207 is provided at one end of the two horizontal plates 209. The end face cam 204 is rotatably connected to the machine box 306 through a cam frame 211 and connected to a linkage motor 213 through a bevel gear pair 212. The bevel gear pair realizes vertical turning of transmission and facilitates linkage control. The linkage motor 213 is fixedly connected to the machine box through a motor frame. The wheel shaft 214 connected to the linkage motor 213 is rotatably connected to the machine box 306 through a bearing seat 215. The wheel shaft 214 is extended at one end (the extended end is also provided with a bearing seat to avoid stable stress) and connected to the rotating shaft of a pressing crank 217 through a synchronous belt mechanism 216. The rotating shaft is fixedly connected to the machine box 306 through a frame 227. The pressing crank 217 is provided with a biasing center pressing pin 218 on the end surface. The pressing pin 218 is movably embedded in the strip-shaped extrusion groove 219 provided in the middle of the connecting rod 206. During the pressing process, the pressing pin can move towards the length direction of the connecting rod. One end of the connecting rod 206 is hingedly connected to the hinge pin of the upper end of the vertical pressing rod 205 through a strip-shaped hinge hole (the strip-shaped hinge hole facilitates the hinge pin to move towards the length direction of the connecting rod during the pressing process). The other end is hingedly connected to a fixed shaft 220. The fixed shaft 220 is connected to the machine box 306 through two fixed seats 226. The lower end of the vertical pressing rod 205 is fixedly connected to a push plate 221. The push plate 221 is elastically embedded in the recess cavity above the vertical pressing block 202. That is, the push plate 221 is provided with two guide holes. The guide holes are penetrated by guide rods 229. The guide rods 229 are fixedly connected to the inner bottom of the recess cavity. A compression spring 230 is sleeved on the guide rod 229. The two ends of the compression spring 230 abut against the bottom of the push plate 221 and the inner bottom of the recess cavity, respectively. Anti-disengagement pieces 231 are fixedly connected to the four corners of the recess cavity. The anti-disengagement pieces 231 prevent the push plate 221 from disengaging from the recess cavity. The two ends of the vertical pressing block 202 are vertically slidably connected to the vertical strip-shaped grooves 222 of two support plates 223 through sliding pins (not labeled in the figure, preferably square head or double pin roller sleeve). The two support plates 223 are fixedly connected to the machine box 306. The outer side surface of the baffle 207 is fixedly connected to a bent baffle 231. The downward extension of the bent baffle 231 can face the blade of the slicing device, thereby playing a protection role and avoiding the danger caused by the exposure of the blade.

[0054] To prevent the dragon fruit from being crushed, the horizontal pressing block 201 and the vertical pressing block 202 are provided with an elastic protective layer 225 on the side facing the pressing surface. The elastic protective layer 225 is provided with multiple conical grooves on the side facing the dragon fruit for easy positioning.

[0055] The aforementioned slicing mechanism 3 includes a slicing blade 301, a connecting rod 302, and a crank 303. The slicing blade 301 has a support plate 304 at its front end, forming a strip-shaped hole with the blade. The middle section has the strip-shaped hole, and one side of the hole forms the blade. The support plate 304 serves to support the dragon fruit when not cutting. The bottom plate of the casing 306, directly opposite the strip-shaped hole, has a transparent strip-shaped hole 309 (wide enough to allow the dragon fruit slices to fall flat onto the fruit plate). This allows the strip-shaped hole to align with the lower tray 6, so that the dragon fruit slices cut by the slicing blade fall onto the tray. Sliding strips 308 and 309 are provided at both ends of the slicing blade 301. 8. A horizontal sliding connection is made to the slide groove 307, which is fixedly connected to the bottom of the housing 306. One end of the connecting rod 302 is hinged to the middle of the rear side of the slicing blade 301, and the other end of the connecting rod 302 is hinged to the crank 303. The crank 303 is rotatably connected to the bearing seat 305 via a rotating shaft, which is connected to the tool power unit. The bearing seat 305 and the slide groove 307 are installed on the bottom of the housing 306. The support plate 304 can move to the feed inlet to place the pushed-in dragon fruit. The housing 306 has a concave cavity structure, and the bottom is suspended and connected to the frame of the discharge conveyor belt via two support beams. The tool power unit includes a tool drive. The motor 310, transmission belt 311, and pulley mechanism are connected. The motor shaft of the tool drive motor 310 is fixedly connected to the drive shaft via a coupling. The drive shaft is rotatably connected to the frame of the discharge conveyor belt. A drive gear 312 is connected to the drive shaft, and a driven gear 313 meshes with the drive gear 312. The driven gear 313 is rotatably connected to the frame of the discharge conveyor belt via a gear shaft and extends through the lower end of the mounting plate 314. The mounting plate 314 is fixedly connected to the frame and housing 306 of the discharge conveyor belt. After the gear shaft extends out of the mounting plate 314, it is connected to the crank-connected rotating shaft and the discharge shaft via the transmission belt 311 and the pulley mechanism, respectively. The drive roller and grooved wheel mechanism of the belt conveyor includes a drive dial 315 and a driven grooved wheel 316. The drive dial 315 is fixedly connected to the rotating shaft and is provided with a drive pin. The driven grooved wheel 316 is fixedly connected to the roller shaft of the drive roller of the discharge belt conveyor. The cylindrical surface of the driven grooved wheel 316 is provided with four arc-shaped grooves and a driven U-shaped groove that fit with the cylindrical surface of the drive dial 315. After the drive dial 315 rotates, it can be engaged into the driven U-shaped groove under the drive pin, thereby realizing the rotation of the gap. The discharge belt conveyor and the slicing mechanism share a power mechanism, which makes the control simpler. Relying on mechanical transmission, the transmission is reliable and stable.

[0056] The aforementioned tray-pushing device 4 includes a tray placement frame 401 and a pusher block 402. The tray placement frame 401 is mounted on the chassis of the discharge conveyor belt 5, and a tray outlet 403 is provided on the side of the bottom facing the discharge conveyor belt 5. The pusher block 402 is vertically and elastically mounted on the slider 404 and extends into the pusher strip hole at the bottom of the tray placement frame 401. The upper end of the pusher block 402 is higher than the bottom surface of the bottom tray and lower than the upper surface. The slider 404 is slidably connected in the pusher sliding groove 405. A gap is provided at the bottom, through which the cylinder rod of the slider 404 and the electric cylinder 407 are connected by the drive arm 406. The electric cylinder 407 is installed on the housing of the discharge conveyor belt 5. The push block 402 is placed in the cavity at the upper end of the slider 404. The bottom of the push block 402 is fixedly connected to the bottom of the cavity of the slider 404 by the push block return spring 413. The upper end surface of the push block 402 has a sloping structure, with the inner side higher than the outer side. Two symmetrical sloping panels are provided outside the discharge port 403 to facilitate the smooth pushing of the push plate onto the conveyor belt.

[0057] Furthermore, the aforementioned push sliding groove 405 is formed by two symmetrical horizontal groove plates 408 arranged opposite each other. The upper ends of the two horizontal groove plates 408 are respectively fixedly connected to the bottom of the plate placement frame 401 through the provided connecting plate 409. The lower ends are respectively provided with two downward extending plates 410, forming a gap between the two extending plates 410. Both extending plates 410 are provided with horizontal sliding grooves 411. The drive arm 406 is provided with limiting pins 412 that are movably embedded in the two horizontal sliding grooves 411 on both sides. Through the limiting effect of the horizontal sliding grooves and limiting pins, the drive arm can be driven more smoothly.

[0058] Example 2: A slicing method for a dragon fruit slicing device, the method is as follows: before feeding, a tray is pushed into the slicing mechanism by a tray pushing device, and a row of dragon fruits is fed into the slicing mechanism by a feeding device. A limiting device is used to limit the position. After limiting, the slicing device repeatedly cuts. Each time it cuts, the tray is pushed forward a distance larger than the diameter of the dragon fruit slice. After the placement of one tray is completed, the next tray is moved on. This continues until the slicing of the row of dragon fruits is completed, and then the cutting of the next row of dragon fruits begins.

[0059] The specific operation process is as follows: Five dragon fruits are loaded onto the grid. Each cut by the blade releases five slices (in a row). The plate moves forward 10cm (this distance is adjusted according to the size of the dragon fruits). Five cuts constitute one cycle, during which a new plate is replaced. The above steps are repeated to complete the slicing of the dragon fruits. Any remaining dragon fruit during slicing is immediately reported to the feeding device. If the slicing cycle deviates from the preset time, the feeding cycle is adjusted promptly to achieve precise feeding, ensuring efficient and non-congested feeding. This invention has a clear concept and the system is easy to control (the control intervals for feeding, blade cycle, and plate / discharge are shown in the diagram). Figure 24As shown in the figure, the advantage is that the entire process from feeding to plating is done manually, resulting in high-efficiency production.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of protection of the claims.
