It can be seen that the fruit pit stuck in the pitting barrel can be dropped out without additional driving.

Description

Technical Field

[0001] The invention relates to the technical field of fruit processing equipment, in particular to a fruit core removing device. Background Art

[0002] Fruit processing equipment needs to remove the core of the fruit. In order to remove the core accurately without losing too much flesh, it is necessary to first place the fruit in the fruit placement position and adjust it so that the center axis of the core is horizontally aligned with the annular cutting blade of the core receiving tube, and then use the core receiving tube with an annular cutting blade at the end to perform the core removal operation. Specifically, the core removal operation is that the core removal drive mechanism drives the core receiving tube to move to the fruit placement position, so that the annular cutting blade of the core receiving tube is inserted into the fruit along the center axis of the fruit core, thereby separating the core and the flesh. The core separated from the flesh is stuck in the core receiving tube, and the core removal drive mechanism then drives the core receiving tube to withdraw from the fruit placement position with the core in the opposite direction. Since the core is stuck in the core receiving tube, it is necessary to set up a drive mechanism to drive the push rod to push the core out of the core receiving tube, which has a complex structure and high implementation cost. Summary of the invention

[0003] The object of the present invention is to provide a fruit core removing device, wherein after the core receiving cylinder has completed the core removing, the fruit core stuck in the core receiving cylinder can be dropped out without additional driving.

[0004] To this end, a fruit pitting device is provided, comprising a fruit placement position, a horizontal pitting cylinder and a pitting driving mechanism. The front end of the pitting cylinder is a circular cutting blade. The pitting driving mechanism drives the pitting cylinder to move to the fruit placement position to perform a pitting operation and then return with the pit.

[0005] The side wall of the core container is provided with a material feeding slot and a material discharging slot;

[0006] It also includes an elastic shifting member extending into the core-containing cylinder at the material shifting slot;

[0007] The material-diverting slot moves forward with the core-containing cylinder until it is completely located in front of the elastic diverting member, and the elastic diverting member is pushed outward by the side wall of the core-containing cylinder to overcome the elastic force and leave the material-diverting slot;

[0008] After the core is removed, the material-moving slot retreats with the core-accommodating cylinder, and the elastic moving member rebounds to extend into the core-accommodating cylinder at the material-moving slot and then moves the core in the cylinder to make it fall out at the material-discharging slot.

[0009] The fruit core removing device, after completing the core removing operation, the core removing driving mechanism drives the core containing cylinder to return with the fruit core, the material shifting slot will return with the core containing cylinder, the elastic shifting member rebounds to extend into the core containing cylinder at the material shifting slot, and then shifts the fruit core in the cylinder to make it fall out at the material discharging slot. It can be seen that the fruit core stuck in the core containing cylinder can be dropped out without additional driving. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Fruit processing equipment such as Figure 1 As shown, a fruit placement position 12 is provided in the frame 1, and the fruit positioning member 3 and the sleeve 4 are both horizontally arranged and arranged on both sides of the fruit placement position 12. The fruit with the central axis of the fruit core horizontally arranged is fed into the fruit placement position 12 from the feed port 11 on the front of the frame 1, and the fruit positioning member 3 and the sleeve 4 move relative to each other to clamp the fruit, thereby positioning the fruit in the fruit placement position. The core removal device ( Figure 1 The fruit peeling device 2 (not shown) and the fruit peeling device 2 arranged on the back of the frame 1 respectively remove the core and peel the fruit, and the fruit pulp obtained after the above treatment falls downward from the discharge port 13 to enter the subsequent processing steps.

[0033] See Figure 2The approaching drive mechanism 5 comprises a left screw 52 and a right screw 54 with opposite spiral directions. A nut slide plate 53 is respectively mounted on the left screw 52 and the right screw 54. As the left screw 52 / right screw 54 rotates clockwise around its own axis, the nut slide plate 53 moves to the left / right. When the left screw 52 / right screw 54 rotates counterclockwise, the respective nut slide plates 53 move to the right / left in the opposite direction. The fruit positioning member 3 is mounted on the nut slide plate on the left screw 52, ​​and the sleeve 4 is mounted on the nut slide plate on the right screw 54. The fruit positioning member 3 and the sleeve 4 have a positioning top block 31 and a limiting top block 41 protruding toward each other on their end faces facing each other. The left screw rod 52 and the right screw rod 54 are connected by a coupling 51. Since the spiral directions of the left screw rod 52 and the right screw rod 54 are opposite, when the driving motor 55 drives the left screw rod 52 and the right screw rod 54 to rotate synchronously in the same direction, the two nut slide plates 53 move in opposite directions on the left screw rod 52 and the right screw rod 54, respectively, thereby driving the fruit positioning member 3 and the sleeve 4 to synchronously approach or move away from each other. The fruit positioning member 3 and the sleeve 4 move relatively close to each other under the drive of the approaching drive mechanism 5 until the positioning top block 31 and the limiting top block 41 respectively press against the watermelon 14 from the left and right sides, thereby positioning the watermelon 14 at the fruit placement position 12. The fruit positioning member 3 and the sleeve 4 are respectively provided with a rotation drive device 8. The fruit positioning member 3 and the sleeve 4 rotate synchronously with the central axis O as the axis under the drive of the respective rotation drive devices 8, thereby driving the watermelon 14 to rotate with the central axis O as the axis, so that the fruit peeling device 2 arranged on the back of the frame 1 can peel the watermelon 14.

[0034] See Figure 3 The fruit peeling device 2 includes a knife holder 23 with a peeling knife assembly 24 installed thereon. The knife holder 23 is installed below the transverse driving mechanism 22. The transverse driving mechanism 22 is installed together with the knife holder 23 below the radial driving mechanism 21. The radial driving mechanism 21 drives the transverse driving mechanism 22 to bring the knife holder 23 close to the fruit placement position 12, and the transverse driving mechanism 22 drives the knife holder 23 to move left and right with the peeling knife assembly 24, so that the peeling knife blade in the peeling knife assembly 24 is aligned with the fruit and thus against the surface of the fruit.

[0035] Fruit peeling device 2 Figure 4 As shown, two sets of parallel peeling knife assemblies 24 are arranged in the knife holder 23. The blades of the peeling knife assemblies 24 of the two sets of peeling knife assemblies 24 have different curvatures and are suitable for peeling large fruits and small fruits respectively. Figure 5The side of the peeling knife 242 is installed at the end of the swing rod 243, the middle part of the swing rod 243 is hinged to the connecting rod 241, and a spring 244 is arranged between the rear part of the swing rod 243 and the connecting rod (the spring can also be replaced by other elastic parts). The peeling knife 242 of the peeling knife assembly 24 is a hollow ring, and the blade 2421 of the peeling knife is arranged on the arc section of the end of the ring and is located on the same side of the swing rod 243 as the spring 244. The spring 244 provides elastic support for the peeling knife 242. In the thick part of the flesh, the peeling knife 242 slightly retreats under the action of elastic force to avoid cutting too deep; in the thin part of the flesh, the peeling knife 242 slightly moves forward under the action of elastic force to avoid cutting too shallow. The swing motor 245 can drive the connecting rod 1 to swing up and down, driving the blade 2421 of the peeling knife 242 to align with the central axis of the fruit.

[0036] like Figure 6 As shown, the sleeve 4 is hollow inside, and the core receiving cylinder 9 and the core removing driving mechanism 7 of the core removing device can be installed horizontally in the sleeve 4, the front end of the core receiving cylinder 9 is a circular cutting blade 91, and the core removing driving mechanism 7 is installed behind the core receiving cylinder 9. The push rod 71 of the core removing driving mechanism 7 extends forward to push the core receiving cylinder 9 forward until the circular cutting blade 91 of the core receiving cylinder 9 is inserted into the fruit to separate the pulp and the core, and the push rod 71 of the core removing driving mechanism 7 retracts backward to drive the core receiving cylinder 9 and the core remaining in the core receiving cylinder 9 back into the sleeve 4. Figure 7 It is a top view of the state where the core container 9 is retracted in the sleeve 4. Figure 8 yes Figure 7 Middle AA section view, Fig. 9 yes Figure 8 Schematic diagram of the position of the elastic toggle member 94 when the middle-capacity core tube 9 is extended forward. Figure 8 , the upper and lower side walls of the core container 9 are respectively provided with a material-discharging slot 92 and a material-discharging slot 93. An axial mounting slot 42 is provided on the sleeve 4 at a position corresponding to the material-discharging slot 92, and a rotating shaft rod 44 is installed between the two side walls of the mounting slot 42, and the rotating shaft rod 44 is located behind the material-discharging slot 92. The elastic toggle member 94 is installed in the sleeve 4, and specifically, the rear part of the elastic toggle member 94 is rotatably mounted on the rotating shaft rod 44 through a torsion spring (not shown in the figure), the middle part is arched in the direction away from the core container 9, and the front part extends into the core container 9 at the material-discharging slot 92 of the core container 9.

[0037] Figure 8 to Figure 9 The core removal driving mechanism 7 drives the core container 9 to extend to the left to perform the core removal operation: the push rod 71 pushes the core container 9 to move to the left, and the material-push-through groove 92 moves forward with the core container 9 until it is completely located in front of the elastic pusher 44. Fig. 9 , the front part of the elastic toggle member 4 is pushed outward by the upper side wall of the core container 9, thereby overcoming the elastic force of the torsion spring and leaving the material-dispensing slot 92. At this time, see Fig.10Taking the core removal operation of apple 15 as an example, the core container 9 extends to the left until it is completely inserted into the apple 15 so that the core and the flesh of the apple 15 are separated, and the core removal drive mechanism 7 then drives the core container 9 to return with the core until Figure 8 When the material-moving slot 92 is retracted with the core-accommodating cylinder 9, the elastic moving member 94 rebounds under the elastic force of the torsion spring and extends into the core-accommodating cylinder 9 at the material-moving slot 92, thereby moving the fruit core in the core-accommodating cylinder 9. After being moved, the fruit core falls out from the discharge slot 93 below and passes downward through the discharge slot 43 on the sleeve 4 corresponding to the discharge slot 93, so that the fruit core stuck in the core-accommodating cylinder 9 can fall out without additional driving.

[0038] Fruit Positioner 3 Fig.11 The positioning drive member 6 is installed in the hollow fruit positioning member 3. Four pins 62 (see the enlarged area D in the figure) are extended forward from the end of the positioning drive member 6 near the positioning top block 31 of the fruit positioning member 3. These pins 62 are distributed around the center of the end face of the fruit positioning member 3. In the area surrounded by these pins 62 on this end face, there is an annular pit 63 facing the annular cutting blade of the core container. Fig.10 In this state, the core-containing cylinder 9 moves forward to the fruit placement position and the annular cutting blade 91 at its front end is inserted into the apple 15, the annular cutting blade 91 passes through the area surrounded by the insertion pin 62 and its front end sinks into the annular pit 63 without touching the surface of the annular pit 63, thereby preventing the annular cutting blade 91 from hitting the positioning drive member 6 and damaging the blade.
