Description

Technical Field

[0001] The invention relates to the technical field of cabbage core removing equipment, and in particular to a cabbage core removing machine. Background Art

[0002] Before deep processing of vegetables such as cabbage and lettuce, the hard core in the middle needs to be removed. There are usually two commonly used core removal methods in the food industry: one is to hire a large number of workers to dig it out manually with a drill. The cabbage core is hard, and it is laborious and easy to hurt the hands when digging it out. It is inefficient, dangerous, and has high labor costs; the other is to use a simple core removal machine. The commonly used core removal machine structure on the market uses a motor to drive a conical drill bit. The worker holds the cabbage and presses the cabbage core into the drill bit, and then takes it out after the core removal is completed. Although this core removal method is more labor-saving than manual digging, the high-speed rotating drill bit has a large forward thrust. If the force of pressing the cabbage in is not well controlled, it is easy to pierce the cabbage, which is more risky. The cabbage needs to be taken out manually after core removal. For high-speed production line operations, multiple machines need to run at the same time to meet the supply and demand of the production line, and the efficiency is also low.

[0025] The present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] Example

[0028] A cabbage core removing machine comprises a workbench 1, on which a rotating mechanism and a switch mechanism are installed, a placing station 2, a core removing station 3 and a blanking station 4 are evenly distributed on the circumference of the workbench 1, a storage table 5 is arranged on one side of the placing station 2, and the storage table 5 is used to store the cabbages waiting to be cored; blanking openings are provided at the core removing station 3 and the blanking station 4 of the workbench 1; the rotating mechanism comprises a dividing plate 6 and three clamping mechanisms 7, the dividing plate 6 is coaxially mounted on the workbench 1, and the clamping mechanism 7 are evenly distributed around the circumference and are installed on the dividing plate 6; the switch mechanism is used to control the clamping and opening of the clamping mechanism 7 at the placing station 2 and the coring station 3; a coring mechanism that can be vertically extended and retracted is arranged below the coring station 3, a conveyor belt 9 is arranged below the blanking station 4, and radially distributed blades 10 are installed between the blanking station 4 and the conveyor belt 9, the blades of the blades 10 face upwards, and the cored cabbage can be cut by the blades 10 when it falls through the blades 10, which is convenient for the subsequent further processing of the cabbage.

[0029] Furthermore, in an embodiment of the present invention, the clamping mechanism 7 includes a ring gear 71, a plurality of gears 72 and a plurality of clamping claws 73, the gears 72 are evenly distributed around the circumference and mesh with the ring gear 71 for transmission, the clamping claws 73 are coaxially fixedly installed with the gears 72, a lever 74 facing the center of the dividing plate 6 is installed on the ring gear 71, a tension spring 75 is installed on the lever 74, the other end of the tension spring 75 is installed on the dividing plate 6, one side of the lever 74 is installed with the tension spring 75, and in the initial state, the lever 74 is blocked and limited by a limit plate 76 on the dividing plate 6; the switch mechanism can move the end of the lever 74 to rotate around the central axis of the ring gear 71. The initial state of the tension spring 75 is an idle state when no cabbage is placed in the clamping mechanism 7. At this time, the tension spring 75 has only a small pulling force to pull the lever 74 against the limit plate 76, and the clamping claws 73 are distributed in a circular array with the center of the ring gear 71. The clamping space formed by the clamping claws 73 in the initial state is the smallest; when the clamping claws 73 are opened, the switch mechanism drives the lever 74 to rotate in the opposite direction of the tension of the tension spring 75, the ring gear 71 rotates, and all the gears 72 rotate in the same direction, and the tightening space formed by the clamping claws 73 becomes larger, which makes it convenient to put the cabbage into the clamping claws 73 at the placement station 2, and also allows the cabbage that has been cored at the blanking station 4 to fall onto the conveyor belt 9; in addition, in order to unify the depth of core removal of the cabbage, after the cabbage is placed in the clamping claws 73, the table top of the workbench 1 can be used as a reference, that is, the bottom of the cabbage is based on the surface that just touches the workbench 1.

[0030] Furthermore, in the embodiment of the present invention, the power drive mechanism of the indexing plate 6 is as follows: a motor reducer 11 is installed below the indexing plate 6, and the output shaft of the motor reducer 11 is fixedly installed with the rotating shaft of the indexing plate 6. The motor reducer 11 is preferably a servo motor, which has the characteristics of high control accuracy and high sensitivity, and can realize dual control of angular displacement and angular velocity.

[0031] Furthermore, in an embodiment of the present invention, the switch mechanism includes a turntable 12, a long shaft 13, a reciprocating mechanism 14 and a toggle mechanism 15. The turntable 12 is coaxially arranged above the dividing plate 6, and the end of the toggle rod 74 extends into the space below the turntable 12. The upper end of the long shaft 13 is coaxially fixedly installed with the turntable 12, and the long shaft 13 rotates downward to pass through the dividing plate 6 and extends out. The reciprocating mechanism 14 is installed at the lower end of the long shaft 13, and the reciprocating mechanism 14 is used to control the reciprocating rotation of the long shaft 13 within an angle range; the toggle mechanism 15 consists of two groups, which are respectively located at the placement station 2 and the core removal station 3, and the toggle mechanism 15 is used to toggle the toggle rod 74 to rotate in the opposite direction of the pulling force of the tension spring 75.

[0032] Further, in the embodiment of the present invention, the toggle mechanism 15 includes a mounting seat 151 and a toggle shaft 152. The mounting seat 151 is fixedly mounted on the edge of the rotating disk 12. The toggle shaft 152 is vertically arranged and the middle part of the toggle shaft 152 is hinged on the side of the mounting seat 151 facing the tension spring 75. The lower end of the toggle shaft 152 extends downward and is located on the side of the toggle lever 74. The lower end of the toggle shaft 152 can only rotate around its hinge axis in the opposite direction of the tension of the tension spring 75. The toggle shaft 152 extends downward and is located on the side of the toggle lever 74 that is not connected to the tension spring 75. When the clamping mechanism 7 rotates and needs to switch the working position, when the indexing plate 6 rotates, the toggle lever 74 of the clamping mechanism 7 rotates in the opposite direction of the tension of the tension spring 75. At this time, the lower end of the toggle shaft 152 can be rotated to be toggled by the toggle lever 74. The toggle lever 74 is not limited by the toggle shaft 152 and smoothly rotates to change the working position state. The switch mechanism does not play the role of opening the clamping claw 73. When the clamping jaws 73 of the placing station 2 and the blanking station 4 need to be opened, the driving mechanism drives the long shaft 13 to rotate in the direction of the tension of the tension spring 75 first. At this time, the dial shaft 152 rotates over the dial rod 74 and is located on the side of the dial rod 74 where the tension spring 75 is installed. Then the driving mechanism drives the long shaft 13 to rotate in the opposite direction. At this time, the dial shaft 152 is limited and cannot rotate around its hinge axis. Therefore, the dial shaft 152 can push the dial rod 74 to rotate, the gear ring 71 rotates with the gear 72 to rotate, the clamping jaws 73 are opened, and the placing station 2 can be opened. When the cabbage is put in, the cabbage at the blanking station 4 falls onto the conveyor belt 9. At this time, the tension spring 75 is stretched and the tension increases. When the cabbage at the placing station 2 is placed, the indexing plate 6 rotates, and the lever 74 leaves the lever shaft 152 and rotates toward the coring station 3. Since the toggle mechanism 15 is not installed at the coring station 3, the clamping claw 73 is always in a state of clamping the cabbage at the coring station 3. Only after the coring is completed and the cabbage is transported to the blanking station 4, the clamping claw 73 can be loosened again under the action of the toggle mechanism 15. In addition, in order to make the toggle shaft 152 always in a vertical state when not in use, a reset spring 153 is installed at the upper end of the toggle shaft 152. The other end of the reset spring 153 can be installed on the fixed seat or the turntable 12. As long as the toggle shaft 152 can be reset to a vertical state after rotation, it is within the protection scope of the present invention.

[0033] Further, in the embodiment of the present invention, the reciprocating mechanism 14 includes a cylinder 141 and a swing arm 142, one end of the swing arm 142 is fixedly mounted on the lower end of the long shaft 13, and the other end of the swing arm 142 is rotatably mounted on the end of the telescopic rod of the cylinder 141, and the cylinder 141 is rotatably mounted below the workbench 1. When the telescopic rod of the cylinder 141 is extended and retracted, it can drive the swing arm 142 to rotate back and forth around the central axis of the long shaft 13. Since the swing arm 142 is fixedly mounted on the lower end of the long shaft 13, the swing arm 142 can control the long shaft 13 to rotate back and forth around its own rotation axis, thereby controlling the reciprocating rotation of the turntable 12 at the upper end of the long shaft 13, and further realizing the reciprocating rotation movement of the dial shaft 152 of the toggle mechanism 15.

[0034] Furthermore, in an embodiment of the present invention, the core removal mechanism includes a cutter head 81, a cutter rod 82 and a rotating lifting mechanism 83, the cutter head 81 is installed at the upper end of the cutter rod 82, the lower end of the cutter rod 82 is dynamically connected to the rotating lifting mechanism 83, and the rotating lifting mechanism 83 is used to control the rotation and vertical lifting of the cutter rod 82.

[0035] Furthermore, in an embodiment of the present invention, the rotating lifting mechanism 83 includes a mounting plate 831, a rotating motor 832, a pulley transmission mechanism 833 and a cylinder 834. The knife rod 82 is rotatably inserted into the mounting plate 831. The rotating motor 832 is rotationally connected to the knife rod 82 through the pulley transmission mechanism 833. The cylinder 834 is installed on the mounting plate 831 and the telescopic rod end of the cylinder 834 is connected to the lower end of the knife rod 82 through a connecting plate 836. In order to enable the cylinder 834 to be able to vertically extend and retract more smoothly, four vertical sliding rods 835 are installed on the connecting plate 836. The rotation of the motor is transmitted to the knife rod 82 through the pulley transmission mechanism 833. The rotation of the knife rod 82 causes the knife head 81 to rotate. At the same time, the vertical extension and retraction of the telescopic rod of the cylinder 834 can drive the knife rod 82 to extend and retract vertically, thereby realizing the movement of the knife head 81 extending upward and retracting downward. In the rotating lifting mechanism 83, the radial rotation between the rod body of the knife rod 82 and the pulley of the pulley transmission mechanism 833 is limited, while the vertical movement is not limited. Therefore, the pulley transmission mechanism 833 can still control the rotation of the knife rod 82 during the vertical extension and retraction of the knife rod 82.

[0036] The cutter head 81 includes a twist drill bit 811 at the tip of the cutter and a conical cutter disc 812 at the tail of the cutter. The twist drill bit 811 can exert a downward pulling force on the cabbage when drilling into the cabbage core, so that the cutter head 81 can drill into the cabbage core more easily to remove the core. In order to facilitate the collection of the drilled cabbage core, a discharge hopper 16 is provided below the core removal station 3 to facilitate the discharge of waste materials.

[0037] The workbench 1 of the present invention is provided with three workstations, and the indexing plate 6 rotates in a manner of 120° at a time, that is, the three clamping mechanisms 7 correspond to the three workstations respectively, and the clamping mechanisms 7 clamp the cabbage as the indexing plate 6 rotates. The switch mechanism can control the clamping mechanisms 7 located at the placement station 2 and the blanking station 4 to open, so as to facilitate the placement of the cabbage and the falling of the cabbage onto the conveyor belt 9. The cabbage core removing machine divides the core removal work of a cabbage into three steps in sequence: (1) the switch mechanism controls the clamping mechanism 7 of the placement station 2 to open, and the core of the cabbage is placed vertically downward on the clamping mechanism 7, and the switch mechanism controls the clamping mechanism 7 to clamp the cabbage;

[0038] (2) The indexing plate 6 rotates 120°, and the clamping mechanism 7 holding the cabbage rotates to the coring station 3. The coring mechanism below the coring station 3 extends upward, and is inserted into the cabbage core from the bottom of the cabbage to remove the core. The removed core falls downward, and the cabbage coring is completed.

[0039] (3) The cored cabbage rotates 120° along with the indexing plate 6 and moves to the blanking station 4. The switch mechanism controls the clamping mechanism 7 at the blanking station 4 to release the cored cabbage, and the cabbage falls freely onto the conveyor belt 9 and is transported away by the conveyor belt 9.

[0040] The above steps are the coring operation flow of a cabbage on the whole machine. In fact, during the production process, every time the dividing plate 6 rotates 120°, the three stations can operate synchronously, that is, every time the dividing plate 6 rotates 120°, the placing station 2 can place a cabbage, the coring station 3 can complete the coring of the cabbage once, and the blanking station 4 can complete the blanking of the cabbage once. During the entire rotation of the dividing plate 6, the coring work of the cabbage can be realized in a streamlined manner, which greatly improves the production efficiency. At the same time, the workers only need to place the cabbage on the clamping mechanism 7 of the placing station 2, and the coring work does not require manual participation, so the safety is relatively high.
