Fruit cutting device with self-cleaning function

Abstract

The fruit cutting device provided by the present invention has a grid knife, a cutting knife, and a nozzle arranged in sequence from back to front, so when the front nozzle sprays water backward, the water flow can wash both the cutting knife and the grid knife. Because the cutting knife is dynamically cut, the cutting knife can move behind the grid knife to avoid it, so as not to affect the nozzle spraying the grid knife, so that both the cutting knife and the grid knife can be sprayed by the nozzle. Since the cutting knife and the grid knife can share the nozzle for cleaning, the structural design of the cleaning component is simple, and the nozzle can be directly installed on the fruit cutting device, so that the fruit cutting device has a self-contained cleaning function.

Description

Technical Field

[0001] The invention relates to the field of fruit cutting, in particular to a fruit cutting device with a self-cleaning function. Background Art

[0002] The current fruit cutting device usually includes a grid knife, a push plate located in front of the grid knife, and a cutting knife located on the back of the grid knife. The fruit is pushed by the push plate until it passes through the grid knife and then dynamically cut by the cutting knife. Since both the grid knife and the cutting knife need to be cleaned, but the cutting knife is located on the back of the grid knife, the two knives will block each other, so the cleaning operation is relatively complicated, and currently most of them are cleaned manually. The inventor considered mechanically cleaning the fruit cutting device and had secretly tried to configure nozzles for the grid knife and the cutting knife for cleaning. A group of nozzles is configured for the grid knife for cleaning. If the grid knife is to be cleaned at multiple angles, multiple groups of nozzles need to be configured. In addition, multiple groups of nozzles are configured for the grid knife, so a large number of nozzles need to be configured, which will make the cleaning component structure complicated and difficult to implement. Summary of the invention

[0003] The technical problem solved by the invention is to provide a fruit cutting device with a self-cleaning function.

[0004] During the research process, the inventor found that the reason why the structure of the cleaning component is complicated is that the grid knife and the cutting knife need to be equipped with nozzles for cleaning respectively. If the grid knife and the cutting knife share the same nozzle, the structure of the cleaning component can be simplified, and the nozzle can even be installed on the fruit cutting device, thereby realizing a fruit cutting device with its own cleaning function.

[0005] The invention provides a fruit cutting device with a self-cleaning function, comprising a grid knife, a push plate located in front of the grid knife and a cutting knife located behind the grid knife. The fruit is pushed by the push plate to pass through the grid knife and then dynamically cut by the cutting knife. The device is characterized in that it comprises a spray head located behind the cutting knife, and the spray head sprays the cutting knife and the grid knife forward to wash.

[0006] The fruit cutting device provided by the present invention has a grid knife, a cutting knife, and a nozzle arranged in sequence from back to front, so when the front nozzle sprays water backward, the water flow can wash both the cutting knife and the grid knife. Because the cutting knife is dynamically cut, the cutting knife can move behind the grid knife to avoid it, so as not to affect the nozzle spraying the grid knife, so that both the cutting knife and the grid knife can be sprayed by the nozzle. Since the cutting knife and the grid knife can share the nozzle for cleaning, the structural design of the cleaning component is simple, and the nozzle can be directly installed on the fruit cutting device, so that the fruit cutting device has a self-contained cleaning function.

[0015] like Figure 1 As shown, the fruit cutting device with self-cleaning function includes a receiving box 1. Figure 2 As shown, the mesh knife 2 is mounted on the front side wall 28 of the material receiving box 1, the material receiving box 1 surrounds the space behind the mesh knife 2, and the cutting knife 3 is mounted inside the material receiving box 1 and behind the mesh knife 2. Figure 3 As shown, two guide rods 4 are respectively provided on the left and right side walls inside the receiving box 1 (the right guide rod is blocked in the figure). Figure 4As shown, the left and right ends of the cutting knife 3 have two grooves 31, respectively, and the two grooves 31 are respectively inserted into the two guide rods 4, so that the cutting knife 3 can move up and down in the receiving box 1 under the drive of the motor 5. Figure 4 As shown, the motor 5 drives the cutting knife 3 to move up and down through the connecting rod 6. The lower end of the connecting rod 6 is a rotating end 61 connected to the motor 5, and the upper end is a sliding end 62. There is a protrusion 63 at the sliding end 62, and a sliding groove 32 is opened on the rear side of the cutting knife 3. The boss 63 is inserted into the slide groove 32, and the motor 5 drives the connecting rod 6 to rotate with the rotating end 61 as the axis: when the sliding end 62 is higher than the rotating end 61, if the connecting rod 6 rotates upward, the boss 63 moves to the left in the slide groove 32, thereby driving the cutting knife 3 to move upward in the material receiving box 1; if the connecting rod 6 rotates downward, the boss 63 moves to the right in the slide groove 32, thereby driving the cutting knife 3 to move downward in the material receiving box 1; when the sliding end 62 is lower than the rotating end 61, if the connecting rod 6 rotates upward, the boss 63 moves to the right in the slide groove 32, thereby driving the cutting knife 3 to move upward in the material receiving box 1; if the connecting rod 6 rotates downward, the boss 63 moves to the left in the slide groove 32, thereby driving the cutting knife 3 to move downward in the material receiving box 1. Figure 1 As shown, five spiral spray heads 7 are installed on the rear side wall 29 of the material receiving box 1, and five first spray heads 8 are installed on the top wall. The spiral spray heads 7 spray the cutting knife 3 and the mesh knife 2 forward. During the spraying, the cutting knife 3 moves up and down inside the material receiving box 1 so that the spiral spray heads 7 spray the mesh knife 2. The first spray heads 8 spray the cutting knife 3 and the mesh knife 2 in a divergent manner toward the gap between the cutting knife 3 and the mesh knife 2. The water flow sprayed by the spiral spray heads 7 and the first spray heads 8 can be discharged from the discharge port 27 (visible Figure 7 ) Leave the receiving box 1.

[0016] like Figure 1 As shown, there is a support box 9 in front of the receiving box 1, and the support box 9 is used to support the fruit to be cut, and surrounds the space in front of the grid knife 2. Figure 4 As shown in the figure, a push plate 10 is installed, and the push plate 10 is located in front of the grid knife 2, and the left and right sides are respectively provided with a left extension piece 111 and a right extension piece 112. Figure 5 As shown, the left and right side walls of the support box 9 are respectively provided with a left groove 121 and a right groove 122 for the left extension piece 111 and the right extension piece 112 to extend out, and the left groove 121 and the right groove 122 have the same structure and size. Since the left and right sides of the device have mutually symmetrical structures, the left side structure of the device is taken as an example for description in this embodiment. Figure 1As shown, the left motor 15 is connected to the left micro screw 14 through the bearing 132 to drive the left micro screw 14 to rotate. The left micro screw 14 is installed on the left side of the support box 9 through the bearing 131, and a left extension piece 111 extending from the left groove 121 is sleeved thereon. The rotation of the left micro screw 14 drives the left extension piece 111 to move forward and backward along the left micro screw 14 in the left groove 121. Similarly, the right extension piece 112 can also move forward and backward along the right micro screw 18 in the right groove 122 under the drive of the right motor 17. If the left extension piece 111 and the right extension piece 112 are driven in the same direction by the left motor 15 and the right motor 17 respectively, the push plate 10 can be driven to move forward and backward in the support box 9.

[0017] like Figure 5 As shown, the top of the supporting box 9 is provided with a feeding port 91 for fruit to be placed in. Figure 1 As shown, there is an upper cover 19 on the support box 9 that can be covered therewith, and nine second nozzles 20 are installed on the top wall of the upper cover 19. The second nozzles 20 spray into the support box 9. In order to prevent water from splashing out from the left groove 121 and the right groove 122 when spraying into the support box 9, as shown in FIG. Figure 1 and Figure 4 As shown, a left waterproof baffle 211 and a right waterproof baffle 212 are installed at the left groove 121 and the right groove 122 respectively. Taking the left groove 121 as an example, Figure 5 As shown, the left groove 121 has a boss 22, and the left waterproof baffle 211 is installed on the boss 22. Installing the left waterproof baffle 211 at the left groove 121 will affect the movement of the left extension piece 111 in the left groove 121. In order to solve this problem, as shown in FIG. Figure 4 As shown, a hole 23 is opened on the left extension piece 111 for the left waterproof baffle 211 to pass through, so that the left extension piece 111 can move forward and backward in the left groove 121 along the left micro screw 14 and the left waterproof baffle 211 under the drive of the left motor 15.

[0018] like Figure 5 As shown, two installation grooves 92 are respectively formed on the left and right sides of the rear end of the support box 9, and two sealing strips 24 are installed at the installation grooves 92. No sealing strip is installed at the lower edge of the rear end of the support box 9. Figure 6 As shown, the support box 9 is connected to the front opening of the material box 1 through the sealing strip 24. When using this fruit cutting device, open the upper cover 19, and the user puts the fruit to be cut between the push plate 10 and the grid knife 2, and the fruit is supported by the support box 9. The push plate 10 pushes the fruit to pass through the grid knife 2. Figure 4As shown, the push plate 10 has densely distributed protrusions 101, which can push the fruit to completely pass through the mesh knife 2. After the fruit is pushed by the push plate 10 and passes through the mesh knife 2, the fruit enters the receiving box 1 and is dynamically cut by the cutting knife 3 located behind the mesh knife 2 in the receiving box 1. The cut fruit is discharged from the discharge port 27 at the bottom of the receiving box 1 (visible Figure 7 ) After the fruit is cut, the second nozzle 20 sprays the inside of the support box 9, the spiral nozzle 7 sprays the cutting knife 3 and the mesh knife 2 forward, and the first nozzle 8 sprays the cutting knife 3 and the mesh knife 2 in a divergent manner toward the gap between the cutting knife 3 and the mesh knife 2. The water flow sprayed by the spiral nozzle 7 and the first nozzle 8 can leave the receiving box 1 from the discharge port 27. Because the support box 9 is only equipped with sealing strips 24 on the left and right sides, and its lower edge is left empty without sealing strips, a gap 25 is formed between the support box 9 and the receiving box 1. Figure 7 As shown, the gap 25 is used for drainage, and the water in the support box 9 can be discharged. Figure 6 As shown, a drainage baffle 26 is provided below the gap 25. The drainage baffle 26 is made of a deformable silicone material. When drainage is required, the water receiving tray automatically moves to the bottom of the discharge port 27. The side wall of the water receiving tray presses against the drainage baffle 26 to exert a backward and upward force on it, so that the drainage baffle 26 is deformed to resist the gap 25. The deformed drainage baffle 26 allows the water in the supporting box 9 to flow into the receiving box 1, and then out of the discharge port 27 (as can be seen). Figure 7 ) leaves the material receiving box 1 and falls into the water receiving tray.
